【Abstract】 A lumping FCC reaction kinetics model of fourteen groups for vacuum residue was proposed. The model establishment was based on Daqing vacuum residue cracking on DVR 1 residue catalyst. With this model, yield predictions under various operating conditions were compared with the product yields of a riser pilot unit and a commercial unit. The comparison results showed that the maximum average deviations of the calculation yields were 0.63% with the former and 0.81% with the latter respectively. The model can be used to predict the product yields at certain set operating conditions.更多还原
