本文对滴流床反应器的强迫非稳态操作进行了实验研究。以钯催化剂上环己烯加氢制环己烷和α-甲基苯乙烯加氢制异丙苯为模型放热反应。控制变量（例如进料组成、进料速率、温度）的变化强烈地影响滴流床反应器的状态和性能。本研究环己烷加氢的目的是寻求周期性操作的条件，使得能够使用更高的平均入口浓度而不蒸发进料混合物。对于α-甲基苯乙烯加氢，目的是发现周期性操作条件，相对于稳态操作，该条件将提高时间平均转化率。
This study concerns experimental investigations of the forced unsteady-state operation of trickle-bed reactors. The hydrogenation of cyclohexene to cyclohexane and α-methylstyrene to cumene on palladium catalysts were taken as model exothermic reactions. Changes in the control variables (e.g. feed composition, feed rate, temperature) strongly influence the regime and performance of a trickle-bed reactor. The aim of the present study of cyclohexane hydrogenation was to seek conditions of periodic operation that would enable higher average inlet concentration to be used without evaporating the feed mixture. For α-methylstyrene hydrogenation, the aim was to discover periodic operating conditions that would improve the time-average conversion relative to that under steady-state operation.
