摘　　要：在甲苯歧化反应中催化剂的积碳主要发生在催化剂表面的较强酸中心上,可以通过催化剂器外再生的方法恢复催化剂的活性。HZSM-5和丝光沸石HM两种催化剂对甲苯歧化反应均有效果,与HM催化剂相比HZSM-5催化剂具有更高的稳定性和抗积碳能力。Coking mainly occurs on the stronger acid center on the surface of the catalys in toluene disproportionation. The activity of the catalyst can be restored by the method of external regeneration of the catalyst. Both HZSM-5 and HM catalysts are effective for toluene disproportionation. Compared with HM catalyst,HZSM-5 catalyst has higher stability and anti carbon deposition ability.
