Batta Louis Bela: Selective adsorption gas separation process. Union Carbide Corporation, January 25, 1972: US3636679 (142 worldwide citation)

Gas mixtures such as air are separated in selective adsorbent beds to produce low-pressure product such as oxygen by simultaneous compressed air-oxygen introduction at opposite ends for partial repressurization, further repressurization with only air, and then product oxygen discharge.

Andrija Fuderer: Enhanced hydrogen recovery from effluent gas streams. Union Carbide Corporation, Alvin H Fritschler, November 19, 1985: US04553981 (103 worldwide citation)

Effluent gas streams for steam reforming, partial oxidation or coal gasification operations are advantageously treated in shift conversion, scrubbing and pressure swing adsorption units for recovery of a purified, hydrogen-containing product gas stream. By recycling a portion of the waste gas remove ...

Steven Hardwick, James V McManus: Process for sorption of hazardous waste products from exhaust gas streams. Novapure Corporation, Steven J Hultquist, June 14, 1994: US05320817 (73 worldwide citation)

A method for cleaning an exhaust gas containing ammonia and at least one silicon-containing compound selected from the group consisting of silane and chlorosilanes, which comprises contacting the exhaust gas with a scavenger comprising a metal salt which forms tight complexes with ammonia. This ammi ...

Eberhard Jacob Dr Dipl Chem: Process and device for selective catalytic nox reduction in exhaust gases containing oxygen.. Man Technologie, June 3, 1992: EP0487886-A1 (72 worldwide citation)

For the operation of an SCR catalyst (5) for nitrogen oxide reduction, it is proposed to spray urea solution finely from a container (8) onto a heated vaporiser/catalyst (3) and, if necessary, to carry out an aftertreatment by means of a downstream hydrolysis catalyst (4). The result is that the red ...

Gas or vapor phase chemical reactions are conducted inside an open loop Stirling cycle apparatus which may operate as a heat engine or as a heat pump. Adsorbent surfaces are associated with the thermal regenerators of the Stirling cycle apparatus, so that pressure swing adsorption separation of reac ...

Le Khac Bi, Bowman Paul T, Hinney Harry R: Highly active double metal cyanide complex catalysts. Arco Chem Tech, November 20, 1996: EP0743093-A1 (65 worldwide citation)

Improved double metal cyanide catalysts are disclosed. The substantially amorphous catalysts of the invention are more active for polymerizing epoxides than conventional DMC catalysts, which have a substantial crystalline component. Polyol products made with the catalysts are unusually clear, have e ...
