Modeling of Particle Growth and Kinetics in Gas Phase Polymerization of Ethylene

فاقد چكيده

By simultaneous solution of the population balance equations for living and dead polymer chains coupled with the method of moments and heat and mass transfer equations at micro- and macroparticle levels in multigrain model, the particle growth, PDI, average molecular weights and concentration of reactants in a semi-batch gas phase ethylene polymerization reactor as a function of time have been predicted. The effect of variation of the concentration of site types 1 and 2 in a two-site Ziegler-Natta catalyst has been discussed .
