ABSTRACT:
Acetylenic compounds are selectively removed by conversion to innocuous materials by contacting hydrocarbon mixtures containing same with a copper-tin and/or lead-zinc aluminate catalyst. In one embodiment, acetylenic compounds are selectively removed from unsaturated hydrocarbon-containing mixtures in a cyclic process comprising alternate contact of the catalyst with a gaseous hydrocarbon phase containing acetylenic contaminants and thereafter of the catalyst with an oxygen-containing gas to regenerate the catalyst.
