在立式固定床高压反应器中，研究了负载于氧化铝和LTL分子筛上的铂、钯催化剂上苯酚气相加氢反应。加氢反应的主要产物为环己酮和环己醇，次要产物为环己烷、环己烯和苯。主要产物的选择性可达99%，转化率受温度、进料速度和氢分压的影响。铂催化剂更适合环己醇的生产，而钯催化剂有利于环己酮的生产。铂催化剂还显示出比钯催化剂高两倍的总转化率。
The vapour-phase hydrogenation of phenol over platinum and palladium supported on alumina and zeolite LTL was studied in a vertical fixed-bed high-pressure reactor. The major products of the hydrogenation reaction were cyclohexanone and cyclohexanol with cyclohexane, cyclohexene and benzene as the minor products. The selectivity for the major products was upto 99%, the conversion being influenced by temperature, feed rate and the partial pressure of hydrogen. Platinum catalysts were found to be better for the production of cyclohexanol while palladium catalysts favoured cyclohexanone production. The platinum catalysts also showed twice as much overall conversion as the palladium catalysts.
