Mesoskopické modelování vývoje morfologie částic polyolefinů
Original language description
The discrete element method (DEM) is employed for the modeling of processes occurring in the polymerization reactor. The first addressed problem is the filling of pores of the catalyst carrier by the polymer phase and its fragmentation in the early stageof particle growth. We investigate the influence of the resistance of the monomer transport to active sites located on the catalyst surface, the influence of the porous structure of the catalyst carrier and the influence of the polymerization temperature on the evolution of the fragmentation of the catalyst carrier. The second addressed problem is the disintegration and the agglomeration of impact polypropylene particles as the consequence of their collisions with the wall of the fluidized reactor or other equipment.
