摘　　要：以某炼油厂催化裂化装置催化剂置换前后的生产运行数据为依据,从原料性质、催化剂以及装置操作条件等方面分析了影响FCC汽油辛烷值变化的主要技术因素。在催化剂方面,控制适宜的稀土氧化物含量和较高的基质活性;在原料性质方面,适度降低饱和烃含量和控制较低的钠含量;在操作条件方面,控制适宜的反应温度和剂油比。通过对汽油辛烷值各个影响因素的系统解析,有助于炼油厂在实际生产中科学有效地进行汽油辛烷值的调节控制。Based on the production and operation data before and after catalyst replacement of a refinery FCC unit, the technical factors affecting the octane number of FCC gasoline are analyzed from the aspects of raw material properties, catalyst and operation conditions of the unit. In terms of catalysts, proper rare earth oxide content and high matrix activity should be controlled. In terms of raw material properties, lower sodium content and moderately lower saturated hydrocarbon content should be controlled. In terms of operation conditions ,the appropriate reaction temperature and the ratio of catalyst to oil should be controlled. Systematic analysis of various influencing factors of gasoline octane number will help refineries to control gasoline octane number scientifically and effectively in actual production.
