摘　　要：生物质是一种资源丰富、环境友好、可再生的廉价资源,生物质催化裂解制备生物油研究众多,但目前生物油制低碳烯烃的工业应用尚处于研发初期,提高低碳烯烃产率是生物油制烯烃研究过程中尚待解决的核心问题之一。研究了棕榈油深度催化裂解制低碳烯烃过程,结果表明,采用PTO催化剂,在反应温度620℃和剂油比7.5的情况下,裂化产物中乙烯收率为7.62%,丙烯收率为19.80%,丁烯收率为12.14%。随着反应温度和剂油比的增加,转化率升高,乙烯和丙烯收率增加,焦炭收率降低,汽油RON增加。Biomass is a resource-rich,environmentally friendly,renewable and cheap resource.There are many researches on catalytic cracking of biomass to produce bio-oil,but the industrial application of bio-oil to light olefin is still in the early stage of research and development.Improving the yield of light olefin is one of the core problems to be solved in the research process of bio-oil to light olefin.The deep catalytic cracking process of palm oil to light olefins was studied.The results showed that the yield of ethylene,propylene and butene were 7.62%,19.80%and 12.14%under the reaction temperature of 620℃and the ratio of catalyst to oil 7.5 with PTO catalyst.With the increase of reaction temperature and the ratio of catalyst to oil,the conversion rate increases,the yield of ethylene and propylene increases,the yield of coke decreases,and the RON of gasoline increases.
