Process for removing carbonyl-sulfide from liquid hydrocarbon feedstocks

摘要

The present invention relates to a process for removing carbonyl sulfide from a liquid olefinic hydrocarbon feedstock comprising (a) passing said hydrocarbon feedstock over an absorbent material comprising zinc oxide and a promoter selected from the group consisting of alumina, silico-aluminas and any combination thereof; and (b) recovering a liquid olefinic hydrocarbon stream having a substantially reduced carbonyl sulfide content.
