Abstract
Acetylenic compounds are selectively removed from hydrocarbon mixtures containing same by oxidation in the presence of a solid copper-manganese-oxygen catalyst. In one embodiment, acetylenic compounds are selectively removed from a conjugated diene mixture containing same by contacting oxygen and a mixture with a copper manganite catalyst under oxidizing conditions.
Claims7
A process for the selective removal of acetylenic contaminants or impurities present in hydrocarbon streams which comprises contacting oxygen and a hydrocarbon-containing mixture contaminated with acetylenic compounds with a catalyst consisting essentially of copper, manganese, and oxygen in which the atomic ratio of copper to manganese varies from about 0.25:1 to about 4:1 under oxidation conditions including a temperature and a mol ratio of oxygen to hydrocarbon sufficient to selectively remove a substantial portion of said acetylenic compounds present in said mixture.
