醚后碳四在ZSM-5分子筛催化剂上的芳构化反应性能

在小型固定床试验装置考察了ZSM-5分子筛催化剂对醚后碳四芳构化反应的催化性能，并进行了催化剂长周期活性稳定性评价。结果表明：在反应温度为380 ℃、反应压力为2.0 MPa、氢油比体积比为300、质量空速为2.0 h-1的条件下，催化剂的长周期运行活性稳定，烯烃转化率大于99%，干气产率小于2%，液化气产率为57%～64%，C5+液体收率为35%～41%，芳烃产率为10%～12%。经过 984 h长周期运行后，芳构化催化剂的积炭量为11.56%。气相产物是优质的裂解制乙烯原料。

STUDY OF AROMATIZATION REACTIVITY OF POST-MTBE C4 ON ZSM-5 CATALYST

The catalytic activity and performance in long operation of ZSM-5 catalyst for post-MTBE C4 aromatization in a fixed bed were studied. The results indicate that at the optimal reaction conditions of 380℃，2.0MPa, WHSV of 2.0h-1 and H2/oil volume ratio of 300, the conversion of olefin exceeds 99%, the yield of dry gas is less than 2.0%, the yield of C5+ is 35%~41%, the yield of LPG is 57%～64%, the yield of aromatic is 10%～12%, and the catalyst shows a stable performance. After 984 h running, the coke deposition on the catalyst is 11.56% and no deactivation of the catalyst is observed. The gaseous product is an excellent material for ethylene production.
