测定了Ru M B/ZrO2 催化剂上选择加氢制环己烯反应过程中苯、环己烯及环己烷浓度随时间变化的c～t曲线 ,获得了苯选择加氢制环己烯反应中各步反应的级数和速率常数等动力学参数 .结果给出 ,苯转化的反应级数对苯为 1,对氢低压下为 2 ,高压下为 0 ;环己烯继续加氢生成环己烷的反应级数对环己烯为 0 ,对氢低压下为 2 ,高压下为 0 .在此基础上建立了苯选择加氢制环己烯各步反应的动力学方程 ,并对动力学方程进行了验证
The c ~ t curves of the concentration of benzene, cyclohexene and cyclohexane in Ru MB / ZrO2 catalysts for the selective hydrogenation of cyclohexene to cyclohexene were determined. And the kinetic parameters such as the number of steps, the rate constant, etc. The results show that the reaction order of benzene conversion is 1 for benzene, 2 for hydrogen and 2 for high pressure, and cyclohexene is continuously hydrogenated to form cyclohexane The reaction order is 0 for cyclohexene, 2 for low pressure hydrogen and 0 for high pressure.A kinetic equation for the reaction of benzene by selective hydrogenation to cyclohexene was established and the kinetic equation Verified
