摘　　要：对减压渣油焦化反应机理和反应过程进行了分析 ,将集总动力学模型用于减压渣油焦化反应过程 ,建立了减压渣油焦化反应的六集总动力学模型。基于网络反应历程和相应假设 ,给出了动力学方程组 ,求得了方程组的解析解 。Lumping kinetic model has been widely used in the research of catalytic cracking and catalytic hydrogenating reaction. The mechanism and process of coking reaction for vacuum residua are analyzed, and the lumping kinetic model is used in the process of vacuum residua coking reaction. A six lumping kinetic model is proposed. According to the model network and its hypotheses, a kinetic equation group is given, and its analytical solution is obtained. The analytical solution and its numerical algorithm to estimate kinetic parameters of coking reaction for vacuum residua are presented.
