PURIFICATION OF ETHYLENE OR PROPYLENE STREAMS CONTAINING CARBON MONOXIDE

摘要

A propylene or ethylene stream containing small quantities of carbon monoxide is contacted with a supported copper oxide catalyst wherein 20 to 95 weight percent of the copper is in the cupric state and the remainder is in a lower valence state. The catalyst is advantageously prepared by treating an oxidized copper oxide catalyst with carbon monoxide or hydrogen.
