Abstract
Ethylene is produced by the selective hydrogenation of acetylene in the presence of carbon monoxide at a concentration of greater than 1% vol, generally greater than 5% vol, and optionally also ethylene by contact at an elevated temperature in the range from 100.degree. to 500.degree. C. with a catalyst comprising a metal oxide or sulphide or mixture of metal oxides or sulphides having hydrogenation activity, for example ZnO either alone or in combination with other metal oxides or sulphides.
