    The work presented in this thesis is concerned with research on the riser of a circulating fluidized bed system for olefin polymerization. In the riser section, fluidization takes place in the transporting slugging mode and polymer particles are produced in the riser in a non-isothermal way. Properties of the polymerization reaction and of the hydrodynamics were studied and their behavior with respect to conditions in the reactor were described. A reactor model was constructed that accurately describes the polymerization process in the circulating slugging fluidized bed. Elements in the reactor model are fluidization, heat transfer and kinetics of the used catalyst system. For heat transfer relations from the open literature are taken. Sorption of monomer into the polypropylene is not considered in the reactor model.
