标题 :Catalyst for hydrocarbon reforming and method of reforming hydrocarbon with the same
发明人：FUKUNAGA TETSUYA
权利人:IDEMITSU KOSAN CO
摘要:The present invention provides a catalyst suitably employed in a variety of hydrocarbon reforming processes and a hydrocarbon reforming process including employing the catalyst in production of hydrogen or synthesis gas. The hydrocarbon reforming catalyst of the present invention contains an alumina carrier containing cerium oxide and, carried on the carrier, component (a), component (b), and optional component (c), the component (a) being at least one platinum group element selected from among ruthenium, platinum, rhodium, palladium, and iridium; the component (b) being cobalt and/or nickel, the component (c) being an alkaline earth metal. When steam reforming, autothermal reforming, partial-oxidation reforming, or carbon dioxide reforming of hydrocarbons is performed through employment of the catalyst, hydrogen or synthesis gas can be produced.

标 题 :Method for paired electrochemical synthesis with simultaneous production of ethylene glycol
发明人：WEINBERG NORMAN L; GENDERS JOHN D; MAZUR DUANE J
权利人:ELECTROSYNTHESIS CO INC; SKA ASS
摘要:Paired electrochemical synthesis reactions in which ethylene glycol is formed at the cathode of a membrane divided cell at high concentrations and current efficiencies, up to 99 percent. Simultaneously, a compatible process is also conducted at the anode of the same electrochemical cell by reacting indirectly generated anode products with organic substrates to form secondary products, such as polybasic acids. The process is especially advantageous in that such secondary products, where appropriate can be further reacted with the ethylene glycol prepared from the catholyte of the same cell to form useful tertiary products, especially polyesters like polyethylene terephthalate. Mole ratios of ethylene glycol and polybasic acid can be controlled through selective use of regeneratable redox reactant.

摘要:Preparation of capped metal oxide nanocrystals comprising a metal oxide shell that are photocatalytically and thermally stable and their dispersions in monomers, oligomers, and polymers, as well as the resulting formulations and nanocomposite films. These nanocrystals are highly monodisperse with nanocrystal size between 3-100 n. Resultant formulations incorporating these nanocrystals and a matrix material are highly stable and result in nanocomposites that have high refractive index, are highly transparent, have minimal to no change in absorption upon thermal or UV processing and are optically transparent in the visible wavelengths with very little or no scattering.
