摘要: 基于不同催化材料对重油裂化性能和碳四烯烃选择性影响的差异,开发了选择性增产碳四烯烃的催化裂化催化剂HBC。HBC催化剂在中国石化石家庄炼化分公司3号催化裂化装置上进行了工业应用,标定结果表明:采用该催化剂后,碳四烯烃收率增加0.52~0.82百分点,液化气中碳四烯烃质量分数增加1.90~3.09百分点,汽油收率增加0.44~1.74百分点,总液体收率增加,焦炭选择性改善。体现了HBC催化剂既具有优异的碳四烯烃选择性,又具有较强的新鲜原料重油裂化能力的特点。

Abstract: Based on the differences of catalytic materials on the cracking performance of heavy oil and the selectivity of butylene, a catalytic cracking catalyst HBC was developed to selectively increase the yield of the target product and has been applied in No.3 FCC unit of SINOPEC Shijiazhuang Refining and Chemical Company. The results showed that the butylene yields were increased by 0.52-0.82 percentage points, the mass fractions of butylene in LPG were increased by 1.90-3.09 percentage points, the gasoline yields were increased by 0.44-1.74 percentage points, the total liquid yields were increased, and the coke selectivity improved. HBC catalyst provides excellent butylene selectivity and heavy oil cracking capacity simultaneously.

Key words: FCC, catalyst, butylene, selectivity
