摘　　要：采用常压微反装置及小型加压评价装置,对镧、铈氧化物以不同的加入方式对研制的重质烃类蒸汽转化催化剂活性、还原性能、抗积炭性能的影响进行了研究。结果表明,以共沉方式加入二氧化铈,更有利于提高催化剂的综合性能。Using micro reactor under atmospheric pressure and laboratory evaluation unit under pressure, the effect of lanthanide sequioxide and eerie oxide by different adding method on the performance such as activity, reducibility and resistance to carbon deposition of the prepared heavy hydrocarbon steam reforming catalysts was studied. The results showed that the comprehensive performance improvement was better by adding eerie oxide using co-precipitation method.
