摘　　要：第三代降低汽油烯烃含量的催化裂化催化剂(GOR-Ⅲ)是在第二代降烯烃催化剂(GOR-Ⅱ)的基础上开发的,其目的在于进一步降低汽油烯烃的含量和提高催化剂的活性稳定性,同时通过提高催化剂的芳构化能力来确保催化裂化汽油的辛烷值不降低.工业应用结果表明:第三代降烯烃催化剂与第二代降烯烃催化剂相比,在相同的操作方案、相近的原料油性质和操作条件下,汽油烯烃含量降低3.5～4.3个百分点;在平衡催化剂上金属镍钒污染水平相当的情况下,催化剂的活性提高3～4个单位,同时汽油的抗爆指数提高,诱导期延长.In order to further reduce the olefin content in Fee gasoline, a GOR-Ⅲ catalyst with improved hydrothermal stability was developed based on GOR-Ⅱ catalyst. The commercial trial results at the FCCU of Wuhan refinery showed that as compared with the GOR-Ⅱ catalyst under similar operation conditions and feedstock properties, using GOR-Ⅲ catalyst the olefin content of FCC gasoline was further reduced by 3.5--4.3 percentages;the micro-activity of the equilibrium catalyst was increased over 3 percentages at the same metals contamination level; the road octane of FCC gasoline increased and the induction period prolonged at the same time.
