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.
