PROMOTION EFFECTS OF NONTHERMAL AR PLASMA ON SILICA SUPPORTED PD CATALYSTS WITH IONIC LIQUIDS FOR SELECTIVE HYDROGENATION OF ACETYLENE

摘要

Selective hydrogenation of acetylene in the presence of ethylene is an important industrial process to remove traces of acetylene for the polyethylene industry since acetylene poisons the ethylene polymerization catalyst. Supported Pd catalysts are widely used to selectively convert acetylene to ethylene in the presence of ethylene, so the further development of Pd-based catalysts with improved catalytic activity and ethylene yield for acetylene hydrogenation is of great interest.
