摘　　要：针对原料重质化和产品轻质化、原料劣质化和产品优质化以及原料供应量减少和产品需求量增加的矛盾,中国石油辽河石化公司两段提升管催化裂化装置中用藏量约70%的CDC催化剂替代LBO-16催化剂进行试验。结果表明:油浆收率下降了1.44%,轻质油收率上升了1.16%,干气产率下降而液态烃收率升高,总液体收率变化不大;在原料中Ni含量高达84.1mg/g的情况下,其H2/CH4的值仍由2.96下降到2.92,并且可以在一定程度上降低汽油中的烯烃含量,而对轻柴油的质量则无明显影响。To meet the challenges presented by the need for producing lighter,better products using heavier and poorer feedstock and by declining feedstock supplies and rising product demand ,PetroChina Liaohe Petro- chemical Company conducted an experiment in its two-stage riser FCC （TSRFCC） unit by replacing LBO-16 catalyst with about 70% CDC catalyst.The experimental results show that the recovery of oil slurry dropped by 1.44% ,that of light oil rose by 1.16% ,that of dry gas declined and that of liquid hydrocarbon increased. The overall recovery of liquids did not change dramatically.Although the Ni density in the feedstock was as high as 84.1mg/g,the ratio of H2/CH4 still dropped from 2.96 to 2.92.Additionally,the olefin content in gaso- line could be lowered to some extent ,while no significant effect was measured on the quality of light diesel oil produced.
