以羰基钌为源,制备了一系列高活性低含量负载钌催化剂.采用XPS、XRD、EDS、AAS和XRF等对催化剂进行表征.对苯的加氢反应进行了研究,考察了催化剂制备方法、加氢方式、反应温度、预热温度、反应压力、时间及空速等对苯加氢反应结果的影响.结果表明,以羰基钌制得的该负载型催化剂反应活性高,反应温度和压力较低,反应时间短,对苯的转化率和环己烷选择性分别达到了99%和98%以上. A series of ruthenium catalysts with high activity and low content were prepared by using ruthenium carbonyl as catalyst.The catalysts were characterized by XPS, XRD, EDS, AAS and XRF etc. The hydrogenation reaction of benzene was studied, and the preparation methods, The effects of hydrogenation mode, reaction temperature, preheating temperature, reaction pressure, time and space velocity on the hydrogenation reaction of benzene were investigated. The results showed that the supported catalyst prepared from ruthenium carbonyl had high reactivity, higher reaction temperature and pressure Low, short reaction time, benzene conversion and cyclohexane selectivity of 99% and 98% respectively.
