摘要： 采用常压连续流动气液反应器,测定了CO气相偶联亚硝酸乙酯再生反应的宏观动力学数据,建立了相应的宏观动力学模型R_A=K_(pNO)反应的活化能E_a=19.46kJ/mol,指前因子A=0.341mol/(m~3·Pa·s).根据气液反应双膜理论,对反应过程进行了分析和参数计算.结果表明,再生反应为一级快反应,反应区在液膜内,反应速率主要受液膜传质控制.求出“本征”反应的活化能为E_a=22.86kJ/mol,指前因子A=1.741×10~8s~(-1).

Abstract: Reaction kinetics data were measured for the regeneration reaction of ethyl nitrite used for the catalytic coupling reaction of carbon monoxide in an atmospheric flowing gas -liquid reactor. The corresponding macroscopic kinetic model was established as the form RA=KpNO with activation energy of 19. 46 kJ/mol and frequency factor of 0. 341 mol/(m3 ·Pa· s). Parameter calculations were carried out with a double - film model of gas - liquid reaction. The results show that the regeneration reaction is a first order quick reaction and the reaction rate is mainly controlled by mass transfer in the liquid film. The activation energy of the intrinsic reaction is 22. 86 kJ/mol and the frequency factor is 1. 741×108s-1.
