英文摘要	National Natural Science Foundation of China [21076171]; State-Key Laboratory of Chemical Engineering of Tsinghua University [SKL-ChE-10A03]; Two improved multigrain models (MGMs) for preparing homopolypropylene and long chain branched polypropylene via propylene polymerization using silica-supported metallocene or dual function metallocene as catalysts are presented in this paper. The presented models are used to predict the intra-particle flow fields involved in the polymerizations. The simulation results show that the flow field distributions involved are basically identical. The results also show that both polymerization processes have an initiation stage and the controlling step is reaction-diffusion-reaction with the polymerization proceeding. Furthermore, the simulation results show that the intraparticle mass transfer resistance has significant effect on the polymerization, but the heat transfer resistance can be ignored.
