摘　　要：分别介绍了直馏汽油、焦化汽油、催化裂化汽油、催化裂解汽油、加氢裂化副产汽油和乙烯裂解副产汽油的烃类组成特点及加工路线选择。直馏汽油品质较好,芳潜较高;焦化汽油品质较劣质,稳定性差;催化裂化汽油辛烷值高;催化裂解汽油芳烃含量高,加氢裂化副产汽油杂质含量低;乙烯裂解副产汽油品质差,稳定性差。得出不同汽油馏分的最优加工路线,受限于市场需求和全厂配置,应根据实际需求合理安排加工路线,才能获得最佳经济效益和社会效益。The hydrocarbon composition features and processing routes of straight-run gasoline,coker gasoline,FCC gasoline,DCC gasoline,hydrorefined gasoline and ethylene cracking gasoline were introduced respectively.Straight-run gasoline had better quality and higher aromatic potential.The quality of coker gasoline was inferior and its stability was poor.FCC gasoline had high octane number.The content of aromatic hydrocarbons in DCC gasoline was high,and the impurity content of hydrocracking by-product gasoline was low.The byproduct gasoline from ethylene cracking had poor quality and stability.The optimal processing routes of different gasoline fractions were obtained,limited by market demand and plant configuration,the optimal processing routes should be rationally arranged according to actual demand,in order to obtain the best economic and social benefits.
