摘要
SD-01甲苯择形歧化催化剂在扬子石化公司67万吨/年甲苯择形歧化装置上工业应用成功并稳定运行,前6个月运行结果为:甲苯转化率为29%,对二甲苯选择性为89%;苯与C8芳烃收率为97%,苯冰点5.47℃。空速、反应温度、反应压力、氢烃比等工艺参数对装置稳定优化运行有重要影响。
SD-01 shape-selective disproportionation catalyst was used in TSD （toluene shape-selective disproportionation） unit, Yangzi Petrochemical Co. Ltd. Half a year＇s operation showed that toluene conversion ratio was 29%, PX/∑ X=89%, （benzene＋C8A） yields was 97%, freezing point of benzene was 5.47℃. Such parameters as weight hourly space velocity, reaction temperature, reaction pressure and n（H2）/n（HC） influenced the optimized operation of the unit greatly.
