摘要

A comprehensive mathematical model is developed for the dynamic calculation of the molecular distributed properties (i.e. MWD and CCD) in a gas-phase, catalytic, ethylene-1-butene copolymerization, FBR, taking into account the various kinetic, micro- and macroscopic phenomena in the reactor. The effects of the two single-site catalyst mass fractions and reactor operating conditions on the production of polyolefins with 'tailor-made' bimodal molecular properties are investigated. It is shown that PE grades with either a bimodal MWD or CCD can be produced in a single FBR, using a mixture of two single-site catalysts under properly selected operating conditions.
