Etherification of FCC Light Gasoline over Mo-Modified β Zeolite Catalyst

Etherification activity of several molecular sieve catalysts for FCC light gasoline was studied in a fixed-bed reactor. H-Beta zeolite was found to be high active than that of others and close to cation exchanged resin catalyst. H-Beta zeolite also showed good activity and selectivity and could not be deactivated easily, and could be easily regenerated after deactivation. In order to further improve etherification activity, the surface acidity and pore structure of zeolite could be modified, by loading different metal oxides. The result showed that the highest conversion of tert-olefin was obtained over Mo/Hβ (1%). The influence of reaction temperature, methanol and tert-olefin molar ratio, reaction pressure, and LHSV on the conversion was investigated. At optimized reaction conditions, tert-olefin conversion of 57.42% had been reached with Mo/Hβ (1%).

二甲醚经低碳烯烃合成汽油组分正辛烷、对二甲苯热力学分析

采用原子矩阵法确定了二甲醚经低碳烯烃制正辛烷和对二甲苯的独立反应数,并通过建立平衡关系,采用文献介绍方法,计算了各个反应的反应热、平衡常数及反应平衡时的平衡组分浓度。经分析表明,反应属放热反应;模型中绝大多数反应能自发进行,并且平衡转化率较高;低温高压有利于正辛烷的生成,而低温低压有利于对二甲苯的生成;丙烯生成正辛烷和对二甲苯的转化率远高于乙烯和丁烯,因此控制中间产物丙烯的含量有利于控制目的产物的产出。
