新型芳烃脱烯烃分子筛催化剂的评价试验

New type zeolite catalyst to remove trace olefins from aromatic hydrocarbons

以新型分子筛为活性组分,与一定比例的载体混合后通过共沉淀法制成新型催化剂。通过动态、寿命等试验,研究了该类催化剂的活性和寿命,结果显示该催化剂的活性及使用寿命均优于白土催化剂,且该催化剂失活后经再生其活性基本不下降,具有较高的工业应用价值和环保意义。

New type zeolite catalyst was prepared with new type zeolite as active component,with boehmite as carrier,and its activities of olefins removal was tested and compared with acid clay.The life and reqenerating tests were also measured .It was found that the new type zeolite catalyst had higher activity and better stability than those of acid clay and it had enough property of regenerating to be applied in industry.
