【摘要】 使用负载型金属镍催化剂对甲基乙烯基酮（MVK）进行了反应动力学研究。于反应温度125—160℃、常压下进行气相加氢试验,导出的动力学方程为: γ_MVK=k·P^0.2_MVK·P_H·P^-0.5_MEK[mol/g cat·min] 测出表观活化能E_■为44kJ/mol,求得阿累尼乌斯方程式中的指前因子A₀为9.20×10³。式中γ_MVK表示反应速度,k为反应速度常数,P_MVK、P_H和P_MEK分别表示甲基乙烯基酮、氢和甲基乙基酮（MEK）的分压（atm）。更多还原

【Abstract】 The hydrogenation kinetics of methyl vinyl ketone over a supported nickel catalyst at a temperature range of 125—160℃ and under atmospheric pressure has been studied. The exponential rate equation obtained from the experimental data is r_MVK=kP_MVK^0.2P_H P_MEK^-0.5（mol/g cat·min） The apparent activation energy E_a is found to be 44 kJ/mol, where r_MVK stands for the reaction rate, k the overall reaction rate constant and P_MVK,P_H,P_MEK the partial pressure of methyl vinyl ketone, hydrogen and methyl ethyl ketone res pectively. The preexponential factor in Arrhenius equation is equal to 9.2×10³.更多还原
