Catalytic effect of cobalt catalysts in the reaction of hydrogenation of ethylene-containing acetylene to ethylene

Abstract

The results of the study on physicochemical and catalytic properties of cobalt catalysts during hydrogenation of acetylene mixed with ethylene are presented. The process of hydrogenation of ethylene-containing acetylene to ethylene on 5% and 7% cobalt catalysts has been studied. The catalytic activity of a palladium catalyst is compared with a cobalt that of one. It is shown that a 7% cobalt catalyst develops a high catalytic selectivity in the hydrogenation reaction of ethylene-containing acetylene without loss of ethylene. Comparative tests of the palladium catalyst and 7% cobalt catalyst in the hydrogenation process of ethylene-containing acetylene have been carried out. It is found that an increase in temperature to 180 ° C in the hydrogenation reaction of ethylene-containing acetylene leads to a decrease in the yield of ethylene.
