Abstract

The kinetics of propylene and ethylene copolymerization in a fluidized bed reactor is considered. Dynamic reactor model based on material balance of monomers, copolymer and copolymerization kinetics has been developed in order to obtain predicted data on monomer flow, copolymer concentration under different process conditions. The complex two-phase model is presented based on two models: well-mixed and two-phase model. The profiles of concentrations and temperatures in microparticles are obtained, and the average concentrations and temperatures at the active sites of the catalyst are determined. The dependences of temperature on the height of the fluidized bed of the reactor at different gas incoming velocity and at different temperature of the monomer input are obtained. Mathematical model that is basis of creating expert control complex of PEBC synthesis process and allow to make quantitative connection between technological parameters of reactors which allows to control technological mode with the acceptable accuracy is presented. Experiment catalytic system is microspheric titanium trichloride (MS-TiCl3) and co-catalyst-diethylaluminum chloride.
