COMAPRISON OF NONTHERMAL ARGON PLASMA TREATMENT VERSUS TRADITIONAL HYDROGENATION ON IONIC LIQUID LOADED SILICA-SUPPORTED PALLADIUM CATALYSTS FOR SELECTIVE HYDROGENATION OF ACETYLENE

摘要

Selective hydrogenation of acetylene in ethylene is an important industrial process to remove traces of acetylene for the polyethylene industry. Commercially, supported Pd catalyst system is used to remove the acetylene contaminant in ethylene feedstock while minimizing ethylene hydrogenation., However, the further development of Pd-based catalysts with improved catalytic activity and ethylene yield for acetylene hydrogenation is still of great interest.
