Study of 2-Dimentional Particle Growth in Catalytic Olefin Polymerization

The polymerization of olefins over heterogeneous catalysts is a rapidly developing industry. In this regard, many researchers are studying the modeling of this process in different lengthscales.Single Particle Modeling (SPM) is using to predict the spatial-temporal evolution of monomer concentration,temperature, and polymerization rate in a single catalyst/polymer particle during the polymerization. Up to now there are several types of SPM found in the literature,such as polymeric flow model (PFM) and multigrain model (MGM), that all of them assume the growing particle isspherical and so, modeling has done in one dimension. In this work, we generalize the simple form of PFM to the 2- dimentional and study the effect of initial shape of particle on properties
