摘要
乙烯低聚制取低碳烃类是回收利用催化干气乙烯资源的有效途径。采用HZSM-5水热处理剂为催化剂,对干气乙烯低聚反应规律进行了研究。结果表明,以提高乙烯转化率和生产LPG为目的,流量以20 mL/min,反应温度以400~450℃为宜,乙烯转化率可达52%,LPG收率可达28%;增加压力对转化率提高有利;提高温度和流速则对烯烃收率有利。
Oligomerization of ethylene into low hydrocarbons was an effective utilization of FCC dry gas.The oligomerization of ethylene in FCC dry gas on steam treated HZSM-5 catalyst was investigated.The results showed that gas flow should be 20 mL/min and temperature should be 400~450 ℃ for increasing ethylene conversion and LPG yield,ethylene conversion and LPG yield could reach 52 % and 28 %;higher pressure is benefit to conversion;higher temperature and flow rate benefit olefin yields.
