dc.description.abstract | Oxychlorination of ethylene to 1,2-dichloroethane is a vital step in the production
of polyvinyl chloride. Polyvinyl chloride is a plastic polymer that
is widely used, especially in construction. The reaction is usually catalyzed
over a CuCl2/γ-Al2O3 catalyst. The neat catalyst is volatile and have limited
activity. The addition promoters, mainly alkali metals and rare earth
metals have shown to have an advantageous effect on the stability, selectivity
and activity of the catalyst. The kinetic of the reaction is complicated
as the catalyst changes from CuCl2 to CuCl and back again during the reaction.
The dynamics of the catalyst causes complications when developing
kinetic reaction models.
A kinetic model previously developed which utilizes the oxidation state of
the catalyst was implemented in three different pseudo-homogeneous reactors:
A dynamic laboratory scale reactor, a steady state industrial reactor
and a steady state industrial test reactor which contains additional
experimental data. The reactor simulations for the laboratory reactor and
industrial reactor were done with kinetics from a neat catalyst and a Kpromoted
catalyst. The industrial test reactor were only simulated with the
K-promoted catalyst.
The simulations for the laboratory scale reactor matched well with the experimental
values. The model was able to predict the spatial-time Cu2+
decently well for both catalysts. However due to lack of reliable experimental
data the validation of the model is uncertain. The industrial scale
simulations are hard to validate as the experiments are done for different
catalysts from the simulated. Some modifications are believed to be needed
and preferably the model should be made heterogeneous to give best results. | en |
