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.
