Acetylene hydrogenation

Ethylene cuts typically comprise 0.5%–2% of acetylene, which is a poison for the polymerization catalysts and should be removed by selective hydrogenation to ethylene

Alumina-supported palladium catalysts are used for selective hydrogenation process, assuring very high activity and selectivity for acetylene hydrogenation. We offer catalysts for selective hydrogenation
