Abstract: A system and apparatus is provided that maximizes mass and energy conversion efficiencies in an integrated thermochemical process for the conversion of fossil fuel or renewable biomass to synthesis gas. The system combines gasification, catalytic conversion of gas to liquid, electricity generation, steam and chilled water generation with a system controller to maximize the conversion efficiency from syngas to merchantable products over the efficiency of syngas alone burned as a fuel. A clean synthesis gas stream is introduced into a catalytic reactor that utilizes specially formulated catalysts to generate liquid fuel from CO and H2 while concentrating CH4 and other combustible, but non-reactive gases in the syngas product stream. The methane rich stream is introduced into an engine for the production of electricity and heat while the unreacted CO and H2 can be recycled to produce additional liquid fuel. Excess heat can be used for other co-located processes and facilities.

Abstract: A catalytic process selectively produces ethanol by contacting synthesis gas (syngas), composed primarily of hydrogen and carbon monoxide, with three catalysts within a reactor. The first catalyst is a hydrogenation promoter comprising Cu—Zn, Mo or Fe with an optional alkali metal additive and an optional support of aluminum oxide, silica, zeolite or clay. The second catalyst is a homologation promoter comprising one or more of the Group VIII metals in free or combined form with a co-catalyst metals consisting of Y or lanthanide or actinide series metals with optional additives and support. The third catalyst is a hydrogenation promoter. This series of catalysts improves the selectivity and yield for ethanol from syngas.

Abstract: The invention is a method of manufacturing a three-way catalyst and the catalyst as well as its use for treating exhaust gas generated by a gasoline internal combustion engine. The catalyst composition comprises a mixture of particles of three different materials. More specifically, it includes a mixture of calcined ceria/zirconia particles impregnated with platinum together with palladium, other calcined ceria/zirconia particles impregnated with only rhodium precious metal, and alumina particles not impregnated with precious metal.

Abstract: The invention is a three-way catalyst, its method of manufacture, and use for treating exhaust gas generated by a gasoline internal combustion engine. The method comprises coating a substrate with mixed metal oxide particles in an amount of 10-30 wt. % based on the weight of the substrate. The mixed metal oxide comprises at least aluminum and rare earth metals of cerium and lanthanum. Precious metals are then deposited on the oxide coating and comprise at least one of platinum and palladium overcoated with rhodium. The total loading of precious metals is about 5-35 g/ft3 of the substrate.

Abstract: An automotive internal combustion engine is equipped with a hydrocarbon adsorber for the purpose of controlling the emissions of unburned hydrocarbons from the vehicle's tailpipe. Regeneration of the adsorber is achieved by an electronic engine controller operating an air pump and a sample pump, using information from an exhaust gas oxygen sensor.

Abstract: An automotive internal combustion engine is equipped with a hydrocarbon adsorber for the purpose of controlling the emission of unburned hydrocarbons from the vehicle's tailpipe. Regeneration of the adsorber is achieved by an electronic engine controller operating a purge air system for drawing desorbed hydrocarbon material into the engine's intake.
