Modelling of morphogenesis of polyolefin particles: catalyst fragmentation

Original language description

A multiscale model of a growing polyolefin particle in heterogeneous catalyzed polymerization reactors is developed. Maximum relevant information can be systematically extracted from particle microscopy images using the method of reconstructed porous media. The spatially 3-D replicas of the particle pore space allow to calculate the effective transport and mechanical properties. Two new modeling techniques approximate catalyst particle fragmentation: Delaunay triangulation generalized into a 3-D space with non-Euclidean metrics and disconnection of the skeleton representation of the solid phase. Predictive mesoscopic modeling of particle morphogenesis is also discussed.
