Experimental investigation and modeling of particle growth and morphology of produced polymer particles were studied in slurry phase propylene polymerization using synthesized Ziegler-Natta catalyst. Polymerization kinetic profile was obtained during polymerization time with repeating experiments to achieve reproduce results of kinetic profile and total yield of polymerization in the same conditions. The mathematical modeling of particle growth was carried out based on the combined model presented in our earlier work. Furthermore, some presented empirical relations were used for mass transfer resistances in the gas-liquid phase of propylene-heptane mixture in the experimental conditions. Most of the important kinetic rate constants were estimated by applying the deconvolution method of GPC data proposed by Soares and Hamielec (1995a) and also by modification on the curve fitting approach presented by Kissin et al. (1999). The proposed mathematical modeling incorporated with mentioned helpful methods show a good confirmation with experimental data particularly in average of particle size for produced PP during polymerization time. Experimental validation of the model could provide industrial applicable features. Furthermore, the proposed model can be extended for other polyolefin polymerization systems as a comprehensive experimental-based model which is an interesting issue in industrial and scientific topics.
