摘要
在研究FX-01催化剂上苯与二乙苯烷基转移反应的工艺条件以及寿命试验的基础上,对该过程进行了动力学试验和液-固反应器模拟。建立了一维拟均相反应器数学模型,并给出了模型的求解方法。结合年产15kt乙苯的实际工业过程,对与烷基化反应配套的烷基转移反应器进行了模拟,计算得到了烷基转移反应器的工艺尺寸:反应器直径为0.35m,高度为9m。催化剂装填量为486kg。合适的工艺操作条件为:反应温度250~260℃,nB/nDEB=8/1~12/1,总质量空速大于5h-1。
The kinetics of diethylbenzene transalkylation with benzene over FX 01 catalyst has been studied,and the rate equation has been obtained The model for liquid solid fixed bed reactor for producing 15000 tons ethylbenzne per year is proposed based on this rate equation The technical dimensions of the reactor are: diameter 0 35m,height 9m,catalyst load 486kg The appropriate operating conditions are:temperature 250~260℃,WHSV of total feedstock over 5h -1 and feed molar ratio of benzene to diethylbenzene 8/1~12/1
