烷基交换作用
The rate constant of global,forward and reverse reaction of transalkylation may be calculated by the proposed pseudo second order kinetic model and the AVRE is only 4%. 类二级反应动力学模型既可给出正向及逆向反应k值,还能使多乙苯转化率的计算平均相对误差降到5%25以下。
The transalkylation of polyethylbenzene, mainly diethylbenzene and triethylbenzene, with benzene catalyzed by tungstophosphoric acid has been studied in stirred autoclave. 采用搅拌高压釜,以磷钨酸为催化剂,研究了苯与多乙苯的烷基转移反应,多乙苯主要是二乙苯和三乙苯。
The performance of ZSM5、TRA and ZSM5-TRA zeolite catalysts(TRA is one kind of the ZSM series zeolites) for the vapour-phase transalkylation of poly-alkylbenzene have been studied. 在连续流动的固定床反应装置上,考察ZSM5、TRA及ZSM5-TRA分子筛催化剂的多烷基苯气相烷基转移催化性能。
The transalkylation behaviours of alkylbenzenes and transalkyllation kinetics of diethylbenzene were investigated in a fixed-bed microreactor over a ZSM5/ZSM11 cocrystal zeolite. 在ZSM5/ZSM11共结晶分子筛、固定床反应装置上对烷基转移和二乙苯与苯烷基转移动力学进行了考察。
