摘要：着重考察了在使用降烯烃催化剂GOR-Q和常规催化剂MLC-500时工艺条件对催化汽油烯烃分布的影响.结果表明:GOR-Q催化剂具有明显降低催化汽油各类烯烃的效果.从碳数分布看,催化汽油中的烯烃主要集中在C5～C7之间.从类型看,单烯烃是催化汽油烯烃的主要存在形式,其中又以正构烯烃和单支链烯烃为主.降低催化汽油烯烃主要是通过小分子烯烃或单烯烃、正构烯烃、单支链烯烃的降低来实现.低温、低空速、高剂油比有利于降低催化汽油中单烯烃、正构烯烃、单支链烯烃和二烯烃含量,但为了减少辛烷值的损失,在降低催化汽油烯烃时首先应采用提高剂油比的方式.
Effect of operation conditions on the olefin distribution of FCC gasoline with GOR-Q catalyst for reducing olefin and normal MLC-500 catalyst were studied emphatically in the paper. The results show evidently that the effect of GOR-Q catalyst on decreasing different kinds of olefins in FCC gasoline. Olefins in FCC gasoline consisted mostly of C_5~C_7 in carbon number distribution and of single olefins or normal olefins and mono-branched-chain olefins. The reduction of gasoline olefin content is achieved by decreasing the olefins above mentioned. Lower reaction temperature,lower weighted hourly space velocity and higher catalyst oil ratio give rise to lower single olefins, normal olefins, mono-branched-chain olefins and diolefins,but increasing catalyst oil ratio is firstly considered to decrease the loss of gasoline octane number.
