【摘要】 在绝热固定床反应装置上比较了3994催化剂和3984催化剂上二乙苯与苯液相烷基转移反应性能。与工业化3984催化剂相比,3994催化剂具有低温和高空速特点。在起始温度245℃、压力3.5MPa、空速7h-1和n(苯)∶n(二乙苯)=1条件下,进行了189h的强化实验,3994催化剂上二乙苯转化率稳定在35%以上,而对于3984催化剂,只有提高温度才能维持二乙苯转化率大于35%。更多还原

【Abstract】 The catalytic behaviors for liquid-phase transalkylation were compared between 3994 and 3984 catalyst in an adiabatic fixed-flow bed. The results showed that 3994 catalyst was superior to commercial 3984 catalyst in higher space velocity and lower reaction temperature, with diethylbenzene conversion of over 35% in a 189-hour test under following condition: initial temperature 245 ℃, 3.5 MPa, WHSV=7 h-1, benzene/diethylbenzene molar ratio=1.3984 Catalyst could only attain diethylbenzene conversion of over 35% at higher temperature.更多还原
