标 题 :Combinatorial synthesis of particulate materials
发明人：KODAS TOIVO T; HAMPDEN-SMITH MARK J
摘要:Methods for fabricating and analyzing particulates having a varying material property such that particulates having a selected desirable material property can be identified. The particulates can be analyzed to determine the particulates having the best properties for a particular application. The particulates can be metals, inorganic compounds, organic compounds and composites. The method of the present invention enables the rapid and economical fabrication and screening of a large number of different compositions.

摘要:Process for the synthesis of binary sulphur compounds, such as rare-earth and transition metal sulphur compounds. This process consists in reacting a rare-earth compound, for example oxide or carbonate, or a transition metal oxide with a sulphur carbon compound such as CS2, in a closed vessel at a pressure of between 1 x 10<5> Pa and 150 x 10<5> Pa. The products obtained are either rare-earth higher sulphides or rare-earth sesquisulphides.

发明人：KODAS TOIVO T; HAMPDEN-SMITH MARK J
摘要:Methods for formulating material systems of varying chemistry and stoichiometry. The material systems include two or more components and can be analyzed to select the system having the best properties for a particular application. Specific examples of materials systems that can be fabricated and analyzed according to the present invention include layers for membrane electrode assemblies (MEA's) that are useful in the construction of fuel cells and similar devices.

标 题 :Catalytic membrane reactor and method for production of synthesis gas
发明人：MUNDSCHAU MICHAEL V
权利人:ELTRON RESEARCH INC
摘要:A solid state membrane for a reforming reactor is disclosed which comprises at least one oxygen anion-conducting oxide selected from the group consisting of hexaaluminates, cerates, perovskites, and other mixed metal oxides that are able to adsorb and dissociate molecular oxygen. The membrane adsorbs and dissociates molecular oxygen into highly active atomic oxygen and allows oxygen anions to diffuse through the membrane, to provide high local concentration of oxygen to deter formation and deposition of carbon on reformer walls. Embodiments of the membrane also have catalytic activity for reforming a hydrocarbon fuel to synthesis gas. Also disclosed are a reformer having an inner wall containing the new membrane, and a process of reforming a hydrocarbon feed, such as a high sulfur-containing diesel fuel, to produce synthesis gas, suitable for use in fuel cells.

标 题 :Process and catalyst for the preparation of a gas mixture having a high content of methane

摘要:A gas rich in methane is prepared by the methanantion of a synthesis gas containing carbon oxides, hydrogen and optionally other gases in the presence of one or more gaseous sulphur compounds, normally in an amount of at least 10 ppm preferably at least 200 ppm by volume, calculated as H2S, with the aid of a catalyst comprising vanadium and/or molybdenum, which during the process is present as one or more sulphides, on a support comprising titanium dioxide. A high activity and a high selectivity for methane are obtained. A further advantage is that, by far, the main constituent of the higher hydrocarbons formed is ethane, which, by conversion into ethylene, is an important raw material in petrochemical synthesis. The selectivity for methane formation may be further improved by promoting the catalyst with compounds, especially sulphides of metals of groups IA, IIA and/or IIIB, particularly cerium. The invention also relates to the catalyst itself which may be prepared by impregnation or coprecipitation techniques.
