摘要
介绍了苯加氢制环己烷过程中的Pt/Al2 O3 催化剂酸中心的产生、积碳、机械杂质的覆盖及水、硫、一氧化碳等对催化剂活性、选择性、寿命的影响 。
The influence of occurrence of acidic core, carbon deposition, coverage of exlernal impurities and other chemicals, such as water, sulphur and carbon monoxide on the activity, selectivity, and lifetime of Pt/Al 2O 3 catalyst used in cyclohexane production is described. The catalyst can be reactivated correspondingly.
