摘要：在甲醇作为FCC部分进料过程研究的可行性分析的基础上,对甲醇在FCC条件下的反应过程进行研究。依据FCC过程特点,采用脉冲微反-色谱装置和RGD催化剂,主要对反应温度、不同浓度甲醇水溶液、不同积炭量催化剂下的甲醇转化进行研究。得出适宜的反应条件为40%(w)甲醇水溶液进料、未积炭催化剂、反应温度550℃～600℃,烃产率可达26.3%～28.1%(w),低碳烯烃占烃组成的67.8%～66.5%(w)。提出甲醇在FCC提升管反应器底部先于原料油进料有利于生成低碳烯烃。初步说明MTO与FCC过程结合的可行性,为进一步实验研究与应用提供依据。
The research of methanol conversion in FCC condition is based on the feasibility analysis that methanol used as a part of FCC feedstock. According to the characteristics of FCC, experiments on RGD catalyst were carried out to study the effects of reaction temperature, methanol concentration, and the coke content of catalyst on pulse mini - scale reactor. The results showed that the highest hydrocarbon yield and its light olefins proportion are 26. 3% -28. 1% (w) and 67. 8%-66.5% (w) respectively, on the equilibrium catalyst and 40% (w) methanol solution feed under 550℃-600℃. Feeding methanol was led into the bottom of riser reactor before oil, which was suggested to produce more light ole fin in FCC unit. The results proved the feasibility of feeding methanol as part of FCC feedstock and provided important reference for its commercial application in certain degree.
