Abstract: An adsorption process is provided to remove oxygen from a hydrogen stream through the use of a copper material in combination with layers of adsorbent to remove water and nitrogen from a hydrogen stream. This process is particularly useful for purification of hydrogen product gas from water electrolyzers with the hydrogen product gas having greater than 99.9 mol % purity.

Abstract: A process is presented for the removal of acetaldehyde from mixture of oxygenates. Acetaldehyde is selectively removed in the presence of other oxygenates like ketones, alcohols and nitriles using an amorphous sodium doped alumina derived from thermally decomposed Dawsonite. The process successfully removes acetaldehyde which can adversely impact catalyst operation.

Abstract: Processes for selectively removing NOx from various gaseous streams are described. The gaseous streams, include, but are not limited to, hydrocarbon process streams, ammonia combustion gas streams, flue gas streams, cement kiln gas streams, and the like. The processes involve contacting the gaseous stream containing NOx with a catalyst in the presence of H2. The NOx is converted to N2 and H2O. The purified gaseous stream has less NOx less than the level of NOx in the gaseous stream. The catalyst consists essentially of metallic copper on a support with optionally Cu2O, CuO, ZrO2, ZnO, TiO, CeO2, NiO, or combinations thereof.

Abstract: Copper sorbents which are resistant to the reduction by hydrogen are used as a guard bed for an acetylene conversion zone. The adsorbents include cuprous oxide, cupric oxide, copper metal, and a halide and are pre-reduced prior to be loaded into the guard bed. The sorbents can remove contaminants that would poison selective hydrogenation catalysts used for a selectively hydrogenating acetylenic compounds in an olefin stream. The sorbents may also selectively hydrogenate the acetylenic compounds.
