Abstract

A selective hydrogenation catalyst for the seletive hydrogenation of unsaturated hydrocarbons, a process for preparing this catalyst and its use. The catalyst of the invention comprises a support, active component Pd, rare earth metals, and auxiliary metal Bi, Ag etc. The catalyst is able to hydrogenate high-unsaturated hydrocarbons such as alkyne with high selectivity at high space velocity while both green oil formation and carbon deposition on the catalyst are very low. It is applicable to an industrial cracking process.
