摘要: 本实验利用脉冲微型反应器-色谱装置,考察了甲醇在四种FCC工业平衡剂,LOSA-1助剂及SAPO-34上的转化反应过程。结果表明:在GOR-Ⅱ上纯甲醇的烃和低碳烯烃收率为19.91%和11.41%,在SAPO-34上为21.90%和16.52%,在LOSA-1助剂上为26.73%和12.01%,当GOR-Ⅱ中的LOSA-1比例为5.00%时,烃和低碳烯烃收率有最大值为27.52%和15.72%;在GOR-Ⅱ上40%甲醇水溶液的烃和低碳烯烃收率为9.09%和6.20%,在SAPO-34上为24.71%和20.08%;而甲醇在CHZ-4、DACS-GQ1及RAG-10上的烃和低碳烯烃收率均较低,RAG-10用量提高后烃和低碳烯烃收率可达到11.12%和6.04%。由实验结果可知:四种FCC工业平衡剂中,甲醇在GOR-Ⅱ上的烃和低碳烯烃收率较好,在GOR-Ⅱ中添加LOSA-1后烃和低碳烯烃收率有所提高,这为研究甲醇在FCC催化剂上制低碳烯烃的反应规律提供了初步的参考。

Abstract: The process of methanol to olefins on four kinds of FCC industrial equilibrium agents, LOSA-1 assistant and SAPO-34 was studied using the pulse microreacter-chromatography devices in the experiment. The results indicated: the hydrocarbon and light olefins yields of methanol conversion were 19.91% and 11.41% on GOR-Ⅱ, 21.90% and 16.52% on SAPO-34, 26.73% and 12.01% on LOSA-1. The hydrocarbon and light olefins yields reached a maximum value 27.52% and 15.72% when LOSA-1 was added into GOR-Ⅱat the ratio of 5%. The hydrocarbon and light olefins yields of 40% methanol solution were 9.09% and 6.20% on GOR-Ⅱ, 24.71% and 20.08% on SAPO-34. But the hydrocarbon and light olefins yields of methanol conversion were low on CHZ-4, DACS-GQ1 and RAG-10 and they can reach 11.12% and 6.04% in the case of increasing the amount of RAG-10.The experiment showed that the hydrocarbon and light olefins yields of methanol conversion were higher on GOR-Ⅱthan on other three kinds of FCC industrial equilibrium agents, the hydrocarbon and the light olefins yields of methanol increased when the LOSA-1 was added into GOR-Ⅱ.Therefore, preliminary reference was provided for the research of the reaction regularity of methanol to olefins on FCC catalysts.
