摘要
在ACE(Advanced Cracking Evaluation)实验装置上,考察了ZSM-5、β、USY分子筛催化裂解F-T合成馏分油制备低碳烯烃的性能,以及温度、剂油质量比、质量空速对β分子筛催化性能的影响。结果表明,反应温度为620℃、剂油质量比为8、质量空速为8 h-1,乙烯收率为4.22%、丙烯收率为31.08%、丁烯收率为19.96%、乙烯+丙烯+丁烯收率为55.24%。
The catalytic performance of ZSM-5,beta and USY zeolites for the preparation of low-carbon olefins from F-T synthetic distillate oil was investigated in ACE experimental facility.The effects of temperature,mass oil-to-solvent ratio and mass space velocity on the catalytic performance of beta zeolites were also investigated.The results showed that the ethylene yield was 4.22%,the propylene yield was 31.08%,the butylene yield was 19.96%,and total light olefin yield (ethylene+propylene+butylene) was 55.24% when the reaction temperature was 620℃,the mass of catalyst to oil ratio was 8 and the mass of space velocity was 8h^-1.
