Different hydrodynamic model for gas-phase propylene polymemation in a catalytic fluidized bed reactor

A comparative simulation study was carried out using the improved well-mixed, constant bubble size and well mixed models. These fluidized bed reactor models, combined with comprehensive kinetics for propylene homo-polymerization in the presence of a multiple active site Ziegler-Natta catalyst. In th...
