摘要： CLCDS-Ⅱ型FCC功能助剂在青岛石化公司1.4Mt/a重油催化裂化（RFCC）装置上的工业应用结果表明，加入占新鲜催化剂补充量0.5%的CLCDS-Ⅱ型功能助剂，不仅具有防止再生器内发生二次燃烧的CO助燃效果，还具有提高液体收率的作用，液化气收率由21.35%提高到23.06%，提高了1.71个百分点；丙烯收率增加，干气、柴油、油浆收率及焦炭产率均有所下降。加剂后对汽油、柴油等产品质量无不良影响。

Abstract: The industrial application of CLCDS-Ⅱ additive in the 1.4Mt/a RFCC unit of Qingdao Petrochemical Company was introduced. The results showed that when the additive dosage was 0.5% of the fresh catalyst make up, it could effectively promote CO combustion and prevent secondary burning. Furthermore, it could improve the product slates, as compared with the base case, the yields of dry gas and coke reduced 0.19 and 0.24 percentage points, respectively; the total liquid yield and LPG yield increased 1.04 and 1.71 percentage points, respectively. Without negative effect on product quality was observed.
