An experiment has been made on the hydrogenation of acetylene contained in a small amount in ethylene with the copper-chromium-manganese oxide catalyst.
It was proved that the catalyst has good selectivity, as follows :
Hydrogenation of ethylene has scarcely occurred until almost all the acetylene contained in ethylene has been hydrogenated to ethylene. But, when ethylene contains absolutely no acetylene, hydrogenation of ethylene occurs quite easily.
Optimum operation conditions are as follows :
Temperature : 200°C; S.V. : 1000; Ratio of hydrogen to acetylene : 2 : 1
