摘要
C_3—C_5轻烃在多种金属改性的HZSM-5沸石催化剂上进行了芳构化试验,并对各种原料以及原料中含有其他成份、影响反应的因素、催化剂的稳定性等进行了研究。结果表明,HZSM-5催化剂对C_3—C_5烃类有较好活性,经金属改性后,芳烃收率可增加20—30％。
Aromatization of C_3-C_5 light hydrocarbons was carried out over a series of metal-modified HZSM-5 catalysts. In addition, the performance of various hydrocarbon feedstocks, factors affecting reactions, and the stability of catalysts were investigated. The results show that HZSM-5 catalyts have better activity, and after modification by metals the yields of aromatic hydrocarbon increase by 20—30％.
