烷基交換作用

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%. 類二級反應(yīng)動力學模型既可給出正向及逆向反應(yīng)k值，還能使多乙苯轉(zhuǎn)化率的計算平均相對誤差降到5%25以下。

The transalkylation of polyethylbenzene, mainly diethylbenzene and triethylbenzene, with benzene catalyzed by tungstophosphoric acid has been studied in stirred autoclave. 采用攪拌高壓釜,以磷鎢酸為催化劑,研究了苯與多乙苯的烷基轉(zhuǎn)移反應(yīng),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. 在連續(xù)流動的固定床反應(yīng)裝置上，考察ZSM5、TRA及ZSM5-TRA分子篩催化劑的多烷基苯氣相烷基轉(zhuǎn)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共結(jié)晶分子篩、固定床反應(yīng)裝置上對烷基轉(zhuǎn)移和二乙苯與苯烷基轉(zhuǎn)移動力學進行了考察。
