PROCESS FOR THE REMOVAL OF ARSINE AND CARBONYL SULPHIDE FROMHYDROCARBON FEEDSTOCKS CONTAINING LIGHT OLEFINS

摘要

Arsine and COS are removed consecutively or simultaneously by passing the hydrocarbon feed over an absorbent material comprising nickel deposited on a support material and wherein the nickel is present both as metallic nickel and as nickel oxide, the total weight of nickel and nickel oxide representing up to about 80% of the weight of the absorbent, the weight ratio of metallic nickel to nickel oxide being of from 0.4 to 2.0, with the proviso that metallic nickel should represent neither less than 10 wt% nor more than 50 wt% of the absorbent.
