摘　　要：Light olefins,such as ethylene,propylene,and 1,3-butadiene,are basic chemical raw materials with increasing global demand of approaching 400 million metric tons per year.During the industrial production of light olefins,traces of alkyne impurities are co-produced and will show great impacts on the polymerization and subsequent processing of olefins.The purification of olefins is therefore regarded as one of the most important and largest chemical separation processes[1].
