摘　　要：以重油为原料,采用多产丙烯催化裂化(FCC)平衡催化剂,在DCR实验装置上考察了重油多产丙烯的FCC反应规律。根据重油FCC反应机理,将原料划分成饱和烃、芳香烃、胶质/沥青质等3个集总,产物划分为干气、液化气(丙烯除外)、汽油、柴油、焦炭、丙烯等6个集总,构建多产丙烯反应网络,利用实验数据求取了27个反应的动力学参数,建立了适用于多产丙烯的重油FCC 9集总反应动力学模型。结果表明:反应动力学参数合理可靠,较好地反映了重油FCC的反应规律;所建模型具有良好的预测性,产品收率计算值与实验值的相对误差在±5.00%以内。With heavy oil as feedstock, fluid cata- lytic cracking（ FCC ） equilibrium catalyst for maxi- mizing propylene yield was adopted, and the FCC re- action rules of heavy oil for maximizing propylene yield were investigated in a DCR pilot plant. Based on the reaction mechanism of heavy oil FCC, the feedstock was classified into three lumps, including saturated hydrocarbon, aromatic hydrocarbon and resin/asphaltene,the products were divided into six lumps,including dry gas, LPG （ except propylene） , gasoline, diesel, coke and propylene etc. The reac- tion networks for maximizing propylene yield were built. The reaction kinetic parameters of twenty-seven reactions were determined by the experimental data, and the nine lumps reaction kinetic model of heavy oil FCC for maximizing propylene yield was established. The results showed that the reaction ki- netic parameter was reasonable and reliable, and the FCC reaction rules of heavy oil could be preferably reflected;the estabilished model had a good predict- ability, the relative error of product yield was within ＋ 5.00% between the calculated value and experi- mental value.
