摘　　要：以降烯烃催化剂为主催化剂,在中型提升管FCC装置上对稀土FCC助剂(RE-Ⅱ)的反应性能进行评价。结果表明:RE-Ⅱ表现出很高的CO助燃活性,增加了轻质油收率,焦炭和干气产率略有降低;而汽油烯烃含量和辛烷值基本不受影响。The reaction performance of novel FCC additive based on rare earth (RE-Ⅱ) was evaluated in a pilot plant riser using an olefin reducing FCC catalyst as base.The results showed that the RE-Ⅱ additive exhibited high activity for CO combustion,increased the yield of light oil and slightly decreased the yield of coke and dry gas,and almost no change in the olefin content and octane number of gasoline.
