摘　　要：采用有机多元醇促进剂合成出了300～800 nm的亚微米NaY分子筛,考察了粒径大小对NaY分子筛性能的影响。利用开发成功的亚微米NaY分子筛制备了催化裂化催化剂,并进行了工业化生产与应用。工业应用结果表明,与常规工业分子筛催化剂相比,转化率提高了0.42个百分点,轻质油收率增加1.14个百分点,总液体收率增加0.86个百分点,焦炭产率降低0.24个百分点。The synthesis of a 300—800nm sub-micrometer NaY zeolite by using organic multi-component alcohol promoter was presented. The effect of crystal size of NaY zeolite on its performancewas investigated. The FCC catalyst was commercially prepared by the sub-micrometer NaY zeolite andapplied in the industry. The commercial application showed that comparing with the conventional zeoliteFCC catalyst, the conversion increased by 0.42%, the light oil yield and total liquid yield increased by1.14% and 0.86% respectively, and the coke yield decreased by 0.24％.
