چکیده

In this study, kinetic of HDPE polymerization in slurry reactor over Ziegler-Natta Catalyst was modeled using the method of moment equations. The kinetic model includes reactions of activation, initiation, propagation, chain transfers and deactivation with the corresponding rate equations. Based on these rate equations, required assumptions and considering five active sites of Z-N catalyst, parameters of polymerization kinetic in two case studies of industrial HDPE were obtained through the suggested algorithm. Equations of zeroth to second moment for living and dead polymers, along with cousumption rate of polymer chains, monomer, cocatalyst, and hydrogen. Modeling results showed good agreement with experimental moleculare weight distribution of polymer in 2 case studies.
