在常压、固定床流动反应器中,进行了偏三甲苯与甲醇混合物在HZSM-5分子筛催化剂上烷基化生成均四甲苯的试验.考察了反应时间、温度、液体空速、配比等因素对均四甲苯收率及产物分布的影响,同时考察了不同焙烧温度、不同硅铝比及有机氟处理的效果,并对比考察了HY与H-丝光沸石(HM)的反应性能,讨论了催化剂酸性与择形性对反应的影响.
In a constant pressure, fixed-bed flow reactor, a mixture of p-trimethylbenzene and methanol was alkylated on a HZSM-5 zeolite catalyst to produce mesitylene, and the reaction time, temperature, liquid space velocity and ratio Factors influencing the yield and product distribution of mesitylene were investigated. The effects of different calcination temperature, different ratio of Si / Al and organic fluorine treatment were also investigated. The reaction performance of HY and H-mordenite (HM) Effect of Catalyst Acidity and Shape Selectivity on Reaction.
