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