【Abstract】 Based on the reaction mechanism of deep catalytic cracking(DCC),reaction rules for all sorts of hydrocarbon molecules were established according to structural oriented lumping method.A(molecular) kinetics model for DCC was established by means of Monte Carlo simulation combined with structural oriented lumping.The results show that the simulation data for product yields and gasoline properties are in good agreement with the plant data in the conditions of two operating states and the model has good prediction and extrapolation performance.更多还原
