    Language:Japanese   Publisher:The Japan Institute of Energy  

    <p>Hydrogenolysis reaction is one of the important reactions to convert lignin into valuable aromatic chemicals. High-pressure hydrogen atmosphere is usually required for hydrogenolysis reaction, which causes high cost of hydrogen transportation and difficulty in handling. Thus we have focused on &quot;in-situ hydrogenolysis&quot; in which both hydrogen production by decomposition of alcohol solvent and hydrogenolysis of the reactant with the hydrogen produced in-situ occur simultaneously. We performed in-situ hydrogenolysis of benzofuran, which is a model compounds of decomposed lignin, in methanol solvent over Pt/Al2O3 catalyst. It was found that only furan moiety of benzofuran was hydrogenated and aromatic compounds like phenol were selectively obtained.</p>

  • In-situ hydrogenolysis of lignin model compound by using hydrogen produced from decomposition of hydrogen carrier

    Language:Japanese   Publisher:The Japan Petroleum Institute  

    Biomass has been attracting more attentions as chemical feedstocks by deoxygenation and hydrogenolysis processes, which require high pressure hydrogen atmosphere. We have proposed new hydrogenolysis process, &ldquo;in-situ hydrogenolysis&rdquo;, in which hydrogen generation by decomposition of hydrogen carrier and simultaneous hydrogenolysis of biomass proceed. We examined the validity of the proposed process by treating benzofuran as lignin model compound in the presence of methanol as hydrogen source and alumina supported platinum catalyst in an inert gas atmosphere. It was found that furan moiety in benzofuran was selectively hydrogenated and monophenolic products were obtained.

  • Upgrading Technology of Super Heavy Oil: Upgrading of Heavy Oil over FeOx-based Catalysts in Sub-/supercritical Water

    From the perspective of diversification of energy resources, a technological development which can convert unused fossil resources into useful fuels has been required. Especially, oil sand bitumen is one of the promising candidates, of which the deposit is larger than that of the petroleum. Consequently, we have developed iron oxide (FeOx) composite catalysts which can convert heavy oil into lighter fuel in superheated steam condition. In this catalytic cracking system, the lattice oxygen in FeOx is main active sites to decompose heavy oil. When the lattice oxygen is consumed during the oxidative reaction, the crystal structure of FeOx changes from hematite to magnetite and the catalyst is deactivated. Therefore, zirconia (ZrO_2) and ceria (CeO_2) that exhibit an activity to produce active oxygen species from water are loaded on FeOx, and the detect of lattice oxygen is regenerated by active oxygen species. Moreover, we have succeeded in improving the resistance to sintering of FeOx by alumina (Al_2O_3 ) addition. In this study, catalytic cracking of oil sand bitumen (abbreviated as bitumen) into lighter fuels such as gas oil and VGO was carried out under high pressure superheated steam and super critical water atmospheres. The effects of reaction atmosphere on the yields of the light fuels and the amount of carbonaceous residue (coke on catalyst and residue on reactor wall) were examined.

    The diffusivities of hydrocarbons within zeolite in gas phase have been measured widely. On the other hand, there have been few reports concerning measurements of the diffusivities of molecules within catalysts in the liquid phase as compared with those in the gas phase, because it is difficult to measure directly and continuously the change in the diffusate concentrations with time due to adsorption and diffusion into the catalysts in the liquid phase. In our recent research, we succeeded in developing a new method for measuring diffusivities within solid catalyst in liquid phase using Raman spectroscopy. Constant volumetric method was employed in this measurement, and diffusion mechanisms of hydrocarbons within solid catalyst were investigated by measuring separately intracrystalline diffusivity and partition factor. Intracrystalline diffusivity directly represents the mobility of molecules within pores. And the partition factor is the ratio of the diffusate concentration in solid catalyst to that in bulk phase, and means the concentration effect. Effective diffusivity is obtained by multiplying the intracrystalline diffusivity by the partition factor. In this manuscript, we review intracrystalline and effective diffusivities of hydrocarbons within porous solid catalyst in gas and liquid phases by introducing our recent research.

    Zeolites have micro pores within their crystals, diameters of which are almost equal to molecular diameters of lighter hydrocarbons. Therefore, zeolite membranes without any pinholes are expected to show high performance for shape selective separation of hydrocarbons. Moreover, by applying the zeolite membrane with catalysis to reaction in series, there is the possibility for producing intermediate species at higher yields than in those using conventional reactors. In this study, catalytic ZSM-5 zeolite membranes were employed to a reaction of methanol to olefins (MTO reaction). The ZSM-5 zeolite catalyst membrane without pinholes was successfully prepared by synthesizing a ZSM-5 zeolite layer on an outer surface of a cylindrical alumina ceramic filter. The membrane was used as the catalytic membrane reactor to recover olefins from methanol. Though olefins were successfully produced at a high selectivity from methanol, the paraffin production was observed at the feed side of the zeolite membrane. In order to inhibit the production of paraffin and aromatics, the acid site distribution of the ZSM-5 zeolite membrane was controlled by CCS method (Catalytic Cracking of Silane method developed in our laboratory). Deactivation of acid sites at the outer surface of the zeolite membrane (feed side of reactant) by the CCS method enable to increase the selectivity of olefins and decrease in the selectivities of paraffin and aromatics.

    The steam reforming to produce hydrogen from the oils derived from the waste plastics such as polyolefins has been investigated. The polyethylene oil and the polystyrene oil were produced by the decomposition of each plastic pellets at relatively low temperature (350-450°C). The experiments of steam reforming of these oils were carried out at the temperature from 650°C to 850°C using commercial Ni/Al2O3 catalyst. Gas yield, gas composition, carbon conversion and coking characteristic were investigated. Both oils from polyethylene and polystyrene were well gasified with very high carbon conversions and low coking rates at the temperatures higher than 800°C. The gas compositions were well agreed with the calculated equilibrium compositions. The coking rate of polyethylene oil was less than that of polystyrene oil and the coking rate was the lowest at 800°C

    From the perspective of diversification of energy resources, a technological development which can convert unused fossil resources into useful fuels has been required. Especially, oil sand bitumen is one of the promising candidates, of which the deposit is larger than that of the petroleum. Consequently, we have developed iron oxide (FeOx) composite catalysts which can convert heavy oil into lighter fuel in superheated steam condition. In this catalytic cracking system, the lattice oxygen in FeOx is main active sites to decompose heavy oil. When the lattice oxygen is consumed during the oxidative reaction, the crystal structure of FeOx changes from hematite to magnetite and the catalyst is deactivated. Therefore, zirconia (ZrO_2) and ceria (CeO_2) that exhibit an activity to produce active oxygen species from water are loaded on FeOx, and the detect of lattice oxygen is regenerated by active oxygen species. Moreover, we have succeeded in improving the resistance to sintering of FeOx by alumina (Al_2O_3 ) addition. In this study, catalytic cracking of oil sand bitumen (abbreviated as bitumen) into lighter fuels such as gas oil and VGO was carried out under high pressure superheated steam and super critical water atmospheres. The effects of reaction atmosphere on the yields of the light fuels and the amount of carbonaceous residue (coke on catalyst and residue on reactor wall) were examined.

    From the perspective of diversification of energy resources, it has been required to develop a new technology to convert unused fossil resources into useful fuels. We have developed mixed metal oxide catalysts and conducted an upgrading of atmospheric residue (AR) under superheated steam using the catalyst. Moreover, we have found that TiO_2-ZrO_2 based catalysts exhibits an acidic cracking activity to decompose for heavy oil under superheated steam atmosphere. In this study, effect of the catalyst compositions on the decomposition activity was examined. Nb_2O_5, Al_2O_3, and CeO_2 were used as third catalytic components to TiO_2-ZrO_2. The TiO_2-ZrO_2-CeO_2 catalyst with the composition of Ti : Zr : Ce = 48 : 48 : 4 exhibited the high and stable activity. Furthermore, the coke formation on the catalyst was successfully suppressed, leading to the stable catalyst activity.

    We carried out the catalytic cracking of pyrolytic oil derived from Loy Yang coal with an iron oxide catalyst bearing Ce, Zr and Al in a steam atmosphere. The durability of iron oxide catalysts was examined by powder X-ray diffractometry(XRD). Iron oxide catalysts required an appropriate amount of Ce, Zr and Al for the cracking of the pyrolytic oil in a steam atmosphere. The steam partial pressure of 87 kPa and the reaction temperature of 773 K were favorable to the durability of the iron oxide catalysts.

    Recently, the demand for useful fuels such as gasoline and kerosene has grown every year. From a viewpoint of energy source diversification, new techniques to produce the fuels from unused heavy oils such as oil sand, oil shale and Orinoco tar are required. Especially, the deposits of oil sand and oil shale are larger than that of crude oil. Thus, we have developed iron oxide catalyst to decompose heavy oils with steam. In this article, we introduce decomposition of waste plastic, a biomass waste, and heavy oil using iron oxide catalyst. Moreover, a consumption-supply cycle of lattice oxygen in steam decomposition of heavy oil using iron oxide catalyst is investigated.

    We carried out catalytic cracking of pyrolytic oil derived from Loy Yang coal with an iron oxide catalyst bearing Zr and Al in a steam atmosphere. Although the pyrolytic oil contained 12.8% on an oil carbon basis of the chemicals that were monocyclic hydrocarbons, phenols and ketones, the total yield of the chemicals by the cracking with the catalyst was more than 25% on an oil carbon basis. The yield of product gas was less than 5.0% on an oil carbon basis. Also, the cracking was effective in decomposing the initial heavy tar. We indicated that the catalyst had a possibility of the production of oxygenated compounds from Loy Yang coal tar via not gasification but the cracking.

    To recover useful lighter hydrocarbons from heavy oil, catalytic cracking of petroleum residual oil was examined. The residual oil was converted into lighter hydrocarbons such as gasoline and kerosene in a steam atmosphere over zirconia-supporting iron oxide catalyst. Steam is decomposed on the catalyst, yielding active oxygen and hydrogen species. Heavy oil fractions are cracked on the catalyst and lighter fractions and coke precursors are generated. The active oxygen species react with coke precursors, producing carbon dioxide. The remaining active hydrogen species are added to the lighter fractions. Therefore, heavy oil was oxidatively cracked on the catalyst without any carbonaceous residue.

    The transalkylation of trimethylbenzene with benzene was investigated over Ferrierite, ZSM-5, Mordenite, β-type and Y-type zeolite catalysts, and the transalkylation activities were compared. Liquid phase transalkylation was performed with a batch reactor under the conditions of 250°C, 3.0MPa, and molar benzene/trimethylbenzene ratio of 1.<br>The transalkylation proceeded over Mordenite, β-type and Y-type zeolites, and Y-type zeolite exhibited the highest catalytic activity of the three catalysts. USY-type zeolite, a dealuminated Y-type zeolite, had a higher activity than Y-type zeolite. This result may be due to the formation of mesopores through dealumination.<br>The effect of the acidity of the zeolites on the transalkylation was investigated using ion (Mg2+, Ca2+, Sr2+, Ba2+)-exchanged Y-type zeolite. The catalytic activity for the transalkylation decreased with lower acidity of the zeolite.

    本研究の目的は,石油中のナフサに含まれるC5成分(n-ペンタン等)を低級オレフィン(エチレン,プロピレン)ならびに芳香族類(キシレン,トルエン)に転換するための,貴金属活性点と固体酸点を近接配置した貴金属内包ゼオライト触媒の開発である.
    油中水滴型マイクロエマルション中で金属微粒子(Rh微粒子,Pt微粒子)を調製し,同微粒子を核として,MFI型ゼオライト(ZSM-5)を形成させた(Rh@ZSM-5,Pt@ZSM-5).このとき添加する金属水溶液濃度,Al量によって金属担持量を0.1wt%~1.0wt%の範囲,ゼオライトの酸点量をSi/Al=∞,200,100,80の範囲で制御することに成功した.
    分子サイズの異なる炭化水素の水素化反応(n-ヘキセン,ベンゼン,トルエン,トリメチルベンゼン)を実施したところ,分子サイズ選択的な水素化反応(トリメチルベンゼンの水素化が進行しない)の進行を確認した.これは,金属微粒子がゼオライト粒子内部に固定化されており,ゼオライト細孔由来の分子篩能により選択的な水素化反応が進行したためである.含侵法触媒では,触媒調製時に金属のシンタリングが進行し,TEM観察では10nm以上の粒子が確認されたが,一方,Pt@ZSM-5とRh@ZSM-5では,金属粒子サイズは約3nm程度であり,内包構造に起因する優れた耐シンタリング性を示した.
    n-ヘキサンとn-ペンタンをモデル原料とし,400~500℃における低級オレフィン合成を実施した.この温度域では,金属を担持していないZSM-5を触媒に用いた場合,n-ヘキサンの転化率は約10%程度,n-ペンタンの転化率は3%程度である.一方,Pt@ZSM-5は極めて高い活性を示し,450~500℃において約50%以上の転化率と高い低級オレフィン選択性を示した.

    From the perspective of diversification of energy resources, a technological development which can convert unused fossil resources into useful fuels has been required. Especially, oil sand bitumen is one of the promising candidates, of which the deposit is larger than that of the petroleum. Consequently, we have developed iron oxide (FeOx) composite catalysts which can convert heavy oil into lighter fuel. In this study, Ti-Fe and Ti-Zr mixed-oxide catalysts were newly developed for oxidative and acid-catalyzed cracking of oil sand bitumen into lighter fuels, respectively. Moreover, it was revealed that the sub-critical water condition was efficient for suppressing coke formation. We also investigated the major reaction pathways for decomposition of bitumen over FeOx-based catalyst under sub-critical water condition, by the numerical simulation based on the lamping model.

    Major objective of this study is to develop a preparation method for zeolite-coating metal nanoparticle with bird-cage structure. Rhodium-complex nanoparticles were first prepared in micro-emulsion solution, followed by formation of MFI zeolite layer on the complex nanoparticles. TEM observation and H2-pulse methods, it was revealed that Rh nanoparticles with the size of approximately 3 nm were completely coated with MFI zeolite (Rh@MFI bird-cage material). Moreover, the Rh nanoparticle in the bird-cage material possessed strong resistance to sintering at high temperature (500~700℃). Because Rh inside the MFI zeolite are oxidized and reduced, a molecule can reach the Rh nanoparticles immobilized inside the MFI zeolite. Finally, MFI zeolite-coating Pt nanoparticle with bird-cage structure was successfully prepared by the same experimental procedure.

Furthermore, these acidic properties were succeeded to be controlled by inserting Fe into their frameworks. MTW nano-sized crystal catalyst thus obtained showed high activity for methylation of 2-methyl-naphtalene. The deactivation of the catalyst could be remarkably prevented in liquid phase reaction under high pressures. MTW nano-sized crystal-layered catalyst membranes were successively prepared. The research on their application to the methylation is continuing, to confirm its validity.

Potassium supported iron oxide catalysis containing zirconia or alumina showed higher allyl alcohol yield from glycerol compared to the glycerol conversion over the iron oxide catalyst without potassium. In addition, it was clarified that polyalcohol conversion with formic acid, which is hydrogen donor, over the potassium supported iron oxide catalysis increase allyl compounds yield. Moreover, developed catalyst was effective for allyl alcohol formation from crude glycerol generated as a by-product in biodiesel production process.

    Main objective of this research is a size-controlled synthesis for zeolite crystal and a development of design method for nano-zeolite catalyst. Various types of zeolites (MFI, TON, MOR, BEA, FAU and MTW) were synthesized and their crystal sizes could be successfully controlled. Especially, in MFI-,MOR-,MTW-,TON-type zeolites, the nano-crystalline zeolites with the size below 100 nm and macro-crystalline zeolite with the size above 1000 nm were obtained.Acrolein production from glycerol and 2,6-dimethyl naphthalene (2,6-DMN) production from 2-methyl naphthalene were conducted using zeolite catalysts. It is found that TON zeolite exhibits a high yield of acrolein above 80 % and that 2,6-DMN is selectively produced using MFI and MTW zeolites. Moreover, the crystal sizes of zeolite affect the product selectivity as well as the catalyst stability, the values of which are drastically improved by applying the nano-crystalline zeolite as a catalyst.

    本研究の目標は、BDFの廃棄物である"アルカリ性グリセリン水溶液"をアセトン、プロピレン、アクロレイン等の石油関連化学物質に変換可能な触媒の開発とその触媒の反応機構の解明である。昨年度は酸化鉄系触媒の最適組成とその調製法を確立した。そこで、本年度はBDF製造時に副生する実際の粗グリセリンの反応を350℃で常圧流通式反応器を用いて実施した。最初に試薬のグリセリンを原料として反応を実施した結果、アリルアルコール→プロピレンの反応(反応1)とアルデヒド→カルボン酸→ケトンの反応(反応2)の二種類が進行した。これら有用成分を合計70%炭素収率(アルデヒドを除くと60wt%弱)で得ることに成功した。さらに、後者の反応はアルカリ金属を触媒に担持することで抑制されるが、前者の反応は抑制されないことを見出し、それが、前者の(反応1)の選択性の向上に繋がることを予測した。一方、粗グリセリンにはカリウムを5wt%、メタノールと有機酸を合わせて30wt%、ガスクロで同定が難しい物質を20wt%以上含まれ、グリセリンは40wt%ほどである。予備実験から期待されたように、粗グリセリンに含まれるカリウムにより(反応2)が抑制され、(反応1)が優先的に進行することを実証した。開発した酸化鉄系触媒の活性種は格子酸素である。反応により消費する格子酸素を水分解により生成する活性酸素によって補充する。そのため、触媒の劣化の主な要因は格子酸素の過度の消費となる。この現象は触媒中の酸化鉄のヘマタイトがマグネタイトに変化することで観測される。分析した結果、反応後の触媒はヘマタイト相を維持しており、粗グリセリンに不純物として含まれる存在するメタノールと有機酸によって触媒が劣化しないことを見出した。

    The main objective of this research is to develop a zeolite membrane exhibiting shape-selective oxidation properties. The major results are described below.
    A)Preparation of mono-dispersed ZSM-5 zeolite nanocrystals: Two types of zeolites with different crystal size, 2.0 micro-meter (micro-zeolite) and 50 nano-meter (nano-zeolite), could be prepared. These zeolites show the same acidity, pore volume, and crystalinity regardless of the different crystal size. Methanol reaction was carried out over the ZSM-5 zeolites, which is a series of reactions from methanol to ether, olefins, paraffins, and aromatics. Though the decrease in the catalytic activity was observed just after the reaction in the micro-zeolite, the nano-zeolite exhibited the high activity and the long life-time.
    B)Selective-deactivation of the acid sites at the outer surface: Acid sites of the zeolite at the outer surface were successfully deactivated by using phenyl-slilane compound. The intermediate of the dimthyl-ether could be selectively produced over the zeolite.
    C)Preparation of nanocrystal-layered membrane: The ZSM-5 zeolite nanocrystals were piled up on an alumina filter. The thickness of the nanocrystals could be controlled in the range from 20 to 40 micrometer. The methanol reaction was carried out using the nanocrystal-layered membrane, and the selectivity of the intermediate such as ether and olefins successfully increased up to 90 %.
    D)Ni-supporting zeolite for selective-oxidation system: Since the acid sites at the outer surface of the zeolite were deactivated, Ni ions could be selectively exchanged for protons at the inner pore of the ZSM-5 zeolite nanocrystals. Accordingly, Ni-supporting zeolite nanocrystals and membrane, which realizes the shape-selective oxidation, could be prepared.

    本研究の目的は、高透過速度と高分離能を有する親水性シリカライトナノクリスタル積層膜の合成と、それによる高度分離プロセスの開発である。昨年度に作製に成功した親水性シリカライトナノクリスタル積層膜を用い、水-アセトン系、および水-エタノール系からの水の選択分離実験を行った。さらに、高度分離プロセスとして、蒸留塔にゼオライト分離膜を併せた複合分離プロセスについてシミュレーターにより経済評価を実施した。親水性シリカライト膜では、水分子はゼオライト結晶表面上のシラノール基と水素結合を形成して透過する。従って、ナノクリスタル粒子間空隙の制御が非常に重要になると考えられた。この点に着目し、ナノクリスタル分離膜の高性能化を検討した。
    ナノクリスタル積層膜では、アルミナフィルター上にシリカライトナノクリスタルを積層させた後、再度水熱合成によってシリカライト保護層を形成させる。そのシリカライト保護層形成時にナノクリスタルが一部成長することで、水の分離性能と分離速度が向上することが明らかとなった。特に、ナノクリスタル層厚さ(ナノクリスタル積層量)、保護層形成時の水熱合成温度と溶液のpHが重要なパラメーターである。これらのパラメーターを適切に設定することで、共沸混合物であり蒸留塔では分離不可能な高濃度エタノール水溶液(エタノール濃度90%以上)においても、親水性ナノクリスタル積層膜を用いることで水の選択分離が可能となった。
    水-アセトン系における蒸留塔とゼオライト分離膜を組み合わせた高度分離プロセスでは、先ず蒸留塔でアセトン濃度80%まで濃縮し、その後ゼオライト膜によってさらに水を分離する方法が効率的であることが明らかとなった。建設コスト、光熱費、人件費を考慮すると約5年後に経費はプラスに転じ、蒸留塔のみのプロセスと比較すると10年後には約10^8の経費削減が可能であることが示された。

    ゼオライトはその結晶内に低級炭化水素の最小分子径とほぼ等しい径の細孔を有するため、高い分子篩能に由来する得意な触媒活性と分離能を示す。しかし、細孔内の拡散速度が極めて遅いため、その性能を最大限に生かしていない。研究実施者はゼオライトの結晶をナノサイズに調製することでこれらゼオライト使用時に問題となる点を克服できるとの着想に至った。
    そのため、平成16年度は、1)単分散ゼオライトナノクリスタルの開発について研究を実施し、珪素、アルミナ源とテンプレート分子が溶解した水溶液と、界面活性剤(O-15)および有機溶媒(シクロヘキサン)を浪合してミクロサイズのエマルションを形成し、その後水熱処理することで、シリカライトとZSM-5について60-200nmの範囲で単分散のゼオライトのナノクリスタルを合成することに成功した。
    そこで、平成17年度は平成16年度に開発したゼオライトナノクリスタルを利用して、次の研究を展開し、所望の成果を得た。
    2)水の選択的高速分離膜の開発:上記1)で合成したシリカライトのナノクリスタルを、アルミナフィルターの表面に吸引濾過固定化し、さらに水熱処理によって固着・薄膜化することで、膜厚が数百nmから数ミクロンの範囲でゼオライト薄膜を合成した。この膜を用いて浸透気化法により高濃度アセトン水溶液(アセトン/水=90/10)から水の選択透過に成功した。透過速度は、緻密な膜に比べて100倍の高速に達した。
    3)メタノールからのオレフィン選択合成用触媒膜の開発:ZSM-5のナノクリスタルを用いて2)と同様の方法により触媒膜を作成した。本触媒膜により、緻密な膜に比べて200倍以上の処理速度でメタノールからオレフィンを60%以上の選択率で合成することに成功した。

    The main objective of this research is to develop a zeolite membrane showing high separation performance in acidic solution. The major results are described below.
    a)Silicalite-1 with hydrophilic properties : A method, called liquid phase oxidation method, was proposed for removing template molecules in as-prepared high siliceous MFI-type zeolite (Silicalite-1) crystals in water solution with hydrogen peroxide. Silicalite-1 treated by this method has many silanol groups in it, and showed high hydrophilic properties, leading to a rigid network of water molecules by hydrogen bonds, in which water molecules are selectively allowed to pass through.
    b)Preparation of nano-crystals of zeolites : First, a micro emulsion was formed by using TEOS, template molecule, surfactant, water and organic solvent. This emulsion was hydrothermally treated to yield mono-dispersed nano-crystals of MFI-type zeolite. The crystal size could be controlled in the range of 60 to 300nm.
    c)Preparation of zeolite membrane with high separation performance : First, nano-crystals of Silicalite-1 were prepared by the method b). Then the crystals were treated by the method a) to yield nano-crystals of Silicalite-1 with hydrophilic properties. The crystals thus obtained were piled on an alumina ceramic filter and hydrothermally treated to fix the crystals on the filter, producing the zeolite membrane. This membrane was applied to the pervaporation of acetone/water and acetic acid/water solutions. The separation factor for water was infinite, and the permeance for water was faster than that of a zeolite membrane without any pinholes by 100 times.

    昨年度では,水/界面活性剤/有機溶媒を反応場に用い,ナノサイズのMFI型ゼオライト(シリカライト)結晶の合成に成功した.そこで、本年度は,ゼオライトナノクリスタルの形成機構について検討すると共に,その機構に基づく結晶サイズ制御を試みた.さらに,アルミニウムを結晶構造に導入し,酸点を持つ均一なMFI型ゼオライト(ZSM-5)ナノクリスタルの調製を試みた.
    シリカとアルミナの原料金属アルコキシドとテンプレートを含む水溶液を界面活性剤/有機溶媒溶液に投入し,マイクロエマルション相を形成する溶液を調製した.この溶液をオートクレーブに投入し,100℃〜160℃の水熱条件下でゼオライトナノクリスタルの合成を行った.原料金属アルコキシド濃度,テンプレート濃度と界面活性剤濃度を変化させることにより,結晶サイズが60nm〜1μmの範囲で制御された単分散なゼオライトナノクリスタルが得られた.更に,MFI型ゼオライト結晶構造内にアルミニウムが導入された,結晶サイズ150nmのZSM-5型ゼオライトナノクリスタルの調製に成功し,固体酸性を有していることをアンモニア昇温脱離法によって確認した.
    結晶サイズ150nmと300nmのZSM-5型ナノクリスタルを調製し,アルミナフィルター上に積層させることにより,触媒膜型反応器を作製した.作製した膜を用いて,メタノールからのオレフィン合成反応(MTO反応)実験を行った.その結果,結晶サイズ150nmのナノクリスタルで作製した膜の方が高活性であり,さらにオレフィンの選択率が向上した.これは,結晶サイズが小さくなるに従い,結晶内における反応原料の拡散抵抗が低減されたためと考えられる.

    ナノ複合反応場によるメタン自熱的改質反応特性を調べるため,複合反応場をもつ触媒の創製を検討した。その結果,シリカ被覆層の内側にNiナノ粒子が固定化され,シリカ被覆層の外側にPtが固定化された複合ナノ粒子を創製することに成功した。Ni触媒反応場とPt触媒反応場がナノスケールの距離で隔離されおり,目的の複合反応場触媒と言える。この触媒を用いてメタン自熱的改質反応の研究を行う過程で,シリカ被覆層内側のNi触媒が極めて特異な触媒反応特性を示すことを見出した。そこで,シリカ被覆Ni触媒を用いて,自熱的改質反応よりもシンプルなメタン部分酸化反応特性を調べた。
    従来の含浸法Ni触媒では,既往の報告通り800℃より低い温度で全く活性を示さず,水素が全く生成しなかったが,シリカ被覆Ni触媒は700℃でも高い部分酸化能を示した。また,生成ガス中の水素/一酸化炭素モル比=1.98とほぼ量論比通りに反応が進行していた。この触媒を用いて700℃で80時間までの反応試験を行ったが,その間の活性低下は全く認められなかった。さらに,この反応系に炭酸ガスを供給し,メタン自熱的改質反応特性を調べたところ,500℃でも充分な水素生成活性が発現し,メタン部分酸化反応よりも反応温度をさらに低下させることができた。
    メタン部分酸化反応後の触媒のTPO測定を行ったところ,含浸法触媒のNiは反応中に完全に酸化されているが,被覆触媒のNiの大部分は金属状態であることがわかった。さらに,反応前処理として空気焼成を行っても,被覆触媒は部分酸化活性をほとんど失わなかった。したがって,Niをシリカで被覆することによって,Niが酸化されにくくなり,そのために低温でも極めて高い活性を示したものと考えられた。

    中間体を目的物質として逐次反応を実施する際,反応率と選択率の両者を同時に向上させるものとして,構造体触媒であるゼオライト触媒膜が考えられる。そこで、MFI型ゼオライト膜型反心器を用いてメタノールの反応を行い、中間体であるオレフィンの選択合成(MTO反応)を検討した。緻密な膜は反応率55〜98%でオレフィン選択率が80%を越えた。この膜の選択性の向上のためには、メタノール供給側の活性点(酸点)を不活性化する必要がある。そこで、最小分子径の異なるシラン化合物を用いて酸点に化学吸着させ、分解することでSi原子を含むコークを生成後、酸化することで酸点上にSiO_2粒子を形成させることで酸点を不活性化した。本法にトリフェニルシランを用いることで、ゼオライト結晶外表面の酸点を選択的に不活性化できることを見いだした。その結果、反応率5〜70%の範囲でオレフィン選択率90%を実現した。さらに、膜透過速度の向上を目的として、ゼオライトナノクリスタルを積層した膜が高い選択性を維持しながら透過速度を向上できることを見いだした。そこで、まずW/Oエマルション技術により約100nmの単分散MFI型ゼオライトナノクリスタルの調製法を開発した。ついで、その結晶を用いて触媒膜を作製し,原料と生成物の膜透過速度の向上を図った。その結果、透過速度を10倍以上に向上できた。さらに、シラン処理することで、芳香族の生成を無視小にできることに成功した。

    ナノスケールの金属微粒子を合成する研究は古くから行われており,現在も種々のナノ粒子を合成するための研究がなされている。本研究では、ナノスケールの金属微粒子を固体担体中に1次元的に配列して固定化することを目的とする。また、その1次元配列を保ったまま金属微粒子を連結させ、ナノスケールの金属ワイヤーを合成することも検討した。金属としては,粒子同士の連結が容易と考えられる金を取り上げ,固体担体にはシリカを用いた。
    塩化金酸を含むマイクロエマルション(ME)にアンモニア水を添加し、金水酸化物微粒子を合成した。ME系としては,主にC-15/シクロヘキサン系を用いた。微粒子合成時の水と界面活性剤のモル比(W)は17とした。その金水酸化物微粒子が分散したMEに、水および担体源であるテトラエトキシシラン(TEOS)を加えてエマルション(EM)とした後、TEOSの加水分解・重縮合を行い,シリカ中に金水酸化微粒子を固定化した。また,乾燥後の試料を空気焼成(200℃,2h)あるいはメタノール還元(80℃)することによって金ナノワイヤーの合成を試みた。
    C-15濃度を0.125Mで一定にして水と界面活性剤のモル比(W)を変化させたところ、Wが低い場合は,球状シリカの中心に金水酸化物微粒子が固定化されたが、Wが40以上のとき、金水酸化物微粒子がシリカ中に1次元的に配列した。Wはミセルの直径に比例するパラメーターであるため,Wが大きい,すなわち太い棒状ミセルが存在するときに微粒子が1次元配列することが示唆された。
    次に、なぜ金水酸化物微粒子が1次元配列する理由について検討した。固定化時のEMの安定性が微粒子の配列に影響しているのではないかと考え,EMの安定性について検討した。その結果、金水酸化物微粒子が1次元配列しなかった組成のEMでは相分離が起こり、1次元配列した組成のEMは分相せずに1相状態を保つことがわかった。したがって、金水酸化物微粒子が1次元配列するには安定なEMが必要であることがわかった。
    最後に、金ナノワイヤーの合成について検討を行った。金水酸化物微粒子が1次元配列した試料を空気焼成およびメタノール還元した。空気焼成した試料では,シリカが棒状から球状に変形し,大部分の金微粒子は凝集していた。しかし,メタノール還元した試料では,金の凝集体は認められず,幅は約5nm、長さは最長で約300nmの金ナノワイヤーが得られた。

    Ferrite materials, which possess highly permeable and insulating, are attracting growing interest, because they might be used at high frequencies as inductors for micro-magnetic devices or wave absorbers for EMI suppression.
    In this study, silica-coated ferrite nanoparticles (SiO_2-coated magnetite (Fe_3O_4), SiO_2-coated cobalt-ferrite (Co_xFe_<3-x>O_4) and SiO_2-coated zinc-ferrite (ZnxFe_<3-x>O_4) were prepared using a water-in-oil microemulsion consisting of water, polyoxyethylen (15) cetylether (surfactant) and cyclohexene (oil). After preparing Fe_3O_4 particles in the solution, an aqueous solution of cobalt chloride or zinc chloride (CoCl_2 or ZnCl_2) was added into the microemulsion containing Fe_3O_4 nanoparticles, and Co-Fe hydroxide complex or Zn-Fe hydroxide complex were formed on the surface of the Fe_3O_4 nanoparticles. TEOS and diluted NH_4OH solution were charged into the microemulsion, and subjected to hydrolysis to produce SiO_2.
    From TEM observations, a ferrite particle was located nearly at the center of each spherical SiO_2 particle. The particle size of Fe_3O_4 and the thickness of the SiO_2 layer were very uniform and varied to within the range of 8.8 nm-13.4 nm and 7.0 nm-20.0 nm, respectively ; furthermore, the size distribution of the Fe_3O_4 particles was very narrow. As the Fe_3O_4 content increased from 3.6 wt% to 10.9 wt%, the saturation magnetization improved from 2.0 emu/g to 6.9 emu/g. Furthermore, the solid solution of Co ions and Zn ions into Fe_3O_4 to form Co_xFe_<3-x>O_4 and Zn_xFe_<3-x>O_4 nanoparticles during air calcination led to an increase in the magnetic properties of the SiO_2-coated ferrite nanoparticles. The coercivity of the SiO_2-coated Co_xFe_<3-x>O_4 nanoparticles increased with increasing amounts of added Co, obtaining a maximum value of 780 Oe around a Co/Fe ratio of 0.3-0.4. The saturation magnetization of the SiO_2-coated Co_xFe_<3-x>O_4 nanoparticles increased with increasing amounts of added Zn, and the maximum value was obtained around a Zn/Fe ratio of approximately 0.1.

    1. We have developed a novel preparation method for supported metal catalysts using water-in-oil microemulsion, an ME method. In this method, Rh particles are partially embedded in SiO_2 supports because the SiO_2 supports are formed by hydrolysis of TEOS around the Rh precursor particle before being synthesized in the reverse micelle. In this work, sintering behaviors of Pt particles were investigated in Pt/Al2O3 catalysts prepared by different preparation method (ME, sol-gel and impregnation method (IMP). Pt/Al2O3 catalysts prepared by ME and sol-gel method possessed high resistance to sintering compared with the catalyst prepared by IMP method, because Pt particles were embedded in the support. Furthermore, resistance to the sintering of Pt particles was improved by pressing the catalysts at 156 MPa. For the endurance test under air flow at 700 ℃ for 12 h, the catalyst prepared using microemulsion and then pressed, the pressed ME catalyst, had greater resistance to sintering of Pt particles than the sol-gel and impregnation catalysts. The pressed ME catalyst exhibited higher activity in NO-CO reaction and maintain the high activity.
    2. We successfully synthesized Rh nanoparticles wholly coated by a nanometer-scale SiO2 layer ring a specific microemulsion system. The thermal stability and the catalytic activity of CO-CO reaction of SiO2-coated Rh catalyst were compared with those of the catalysts prepared by ME, sol-gel and IMP methods. In the SiO2-coated Rh catalyst, all the Rh particles were covered by the SIO2 layer and remained small even after the thermal treatment at 900 ℃ for 12 h. It is concluded that migration of Rh particles of the SiO2-coated Rh catalyst was restrained by the SiO2 layer, resulting in the highest resistance to sintering. As a result, this catalyst had the highest activity in NO reduction by CO after thermal treatment at 900 ℃ for 12 h.

    (1)バインダー分子を用いた異種微粒子の液相中における配置制御
    新規バインダー分子の合成は困難であったため,市販試薬をバインダー分子として用いた異種微粒子の配置制御について検討した。バインダー分子としてはジアミンを用い,異種金属微粒子としてはジアミンとの親和性を考慮してRhとMgを取り上げた。合成条件を種々検討した結果,安定化剤で保護されたRh錯体微粒子にバインダー分子の片端が吸着し,バインダー分子のもう片端にMgイオンが吸着した複合超微粒子(15nm)を合成することに成功した。したがって,液相中においてRhとMgをある一つの相互配置に制御することができた。
    (2)異種金属微粒子の担体上における相互配置制御
    得られたRh-バインダー-Mgの複合超微粒子を析出法によってシリカ担体上に固定化し,熱処理を行った。その結果,MgO微粒子がRh金属微粒子の表面にのみ存在する相互配置をシリカ担体上において構築することができた。なお,従来法で調製したMgO/Rh触媒ではRhとMgOのシリカ上における相互配置はランダムであった。これらの結果は,化学分析によって確認した。さらに,本触媒と従来法触媒のCO水素化反応特性を調べたところ,本触媒では,従来法触媒では全く認められなかった,RhとMgの協奏効果(活性向上とアルコール選択性向上)が明確に認められた。すなわち,反応特性からも,担体上におけるRhとMgの相互配置制御に成功したことを示すことができた。

    Rh微粒子調製時の溶液の温度を40℃〜70℃で変化させることにより、Rh粒子径のみを3.0nm〜4.9nmの範囲で制御することができた。また、TEOS加水分解時のTEOS添加量、アンモニア濃度を変化させることによる、SiO_2層厚み、SiO_2細孔構造を制御することができた。SiO_2層の平均細孔径は約1.0nmであり、アンモニア量によって細孔容量が変化した。これらのRh-SiO_2包接微粒子を用いてCO水素化反応を行ったところ、反応律速下で水素化反応が進行していることが明らかとなった。一方、このRh粒子径範囲では、生成物選択性はほぼ一定であった。SiO_2細孔容積が大きい包接微粒子ほど、触媒活性が高くなり、さらに工業的に有用な炭素数2以上の含酸素化合物が選択率40%以上で得られた。これは、SiO_2細孔容積が増大する、すなわちSiO_2の空隙が大きくなるに従い、気相と接触可能なRhの活性サイトが増加したためと考えられる。

    In this study, we prepared TiOィイD22ィエD2 catalysts for the photo-decomposition of organic compounds. Titania ( TiOィイD22ィエD2) particles were prepared by hydrolysis of titanium alkoxide, titanium tetra-n-butoxide (TTB), in water-in-oil microemulsion. Crystal size of TiOィイD22ィエD2 thus obtained was 8.5 nm and much smaller than that of commercial TiOィイD22ィエD2, P-25. The surface area of TiOィイD22ィエD2 was larger than that of commercial TiOィイD22ィエD2 (P-25) because of the small crystal size. In photo-decomposition of acetic acid, the catalytic activity of the TiOィイD22ィエD2 prepared by this method was higher than that of P-25. The high activity was attributed to the high surface area.
    Moreover, to enhance the catalytic activity for the photo-decomposition of organic compounds at a low concentration in waste water, active carbon (AC)-supported TiOィイD22ィエD2 catalysts were prepared. TTB and phenolic resin were used as a precursor of TiOィイD22ィエD2 and active carbon, respectively. Colloidal TiOィイD22ィエD2 particles were synthesized by hydrolysis of TTB in a methanol solution of phenolic resin. The phenolic resin containing TiOィイD22ィエD2 particles was carbonized in NィイD22ィエD2 in the temperature range from 400℃ to 800℃. Anatase titania with a crystal size of approximately 7.0 nm was obtained. Photo-decomposition of acetic acid was carried out as a model reaction. Air-activation was conducted to increase the surface area of carbon support, because the increase in the surface area led to the enhancement of the absorbing ability of TiOィイD22ィエD2 catalyst for acetic acid. The photocatalytic activity was increased with the increasing surface area.

    In this work we have succeeded in preparing Pt-size controlled Pt/AlィイD22ィエD2OィイD23ィエD2 catalysts by a novel preparation method using microemulsion. When Pt-complex nanoparticles in microemulsion were used in the preparation, the Pt particle size of the catalyst varied with the precursor type in microemulsion. The size of the Pt particles of the prepared Pt/AlィイD22ィエD2OィイD23ィエD2 catalysts could be controlled in range of 3.8-23.4 nm by changing the length of alkyl group in the complex-forming agents.
    The catalytic performances in NO-CO reaction over those Pt-size controlled catalysts thus prepared were investigated and compared with the catalytic performance of the Pt/AlィイD22ィエD2OィイD23ィエD2 catalysts prepared by the conventional impregnation method. It was found that the catalysts prepared using microemulsion exhibited a higher activity for NO reduction by CO than the one prepared by the impregnation method.
    The thermal stability of platinum particles of Pt/AlィイD22ィエD2OィイD23ィエD2 catalysts against sintering was examined heating the catalysts at 700℃ under air flow for 12 h. The platinum particles of the catalysts prepared by this method were considered to be difficult to sinter, because the particles were partly embedded in the alumina. However, the particle size became larger due to sintering. It was considered that the platinum particles in the catalysts could move easily because of the large pore size of alumina support. In order to avoid aggregation of the particles, the pore size was decreased by pressing the catalysts. The catalyst thus pressed exhibited extremely high thermal stability compared with the catalysts before pressing.
