Abstract Toluene Disproportionation reaction is an industrial approach for the productionof benzene and xylenes from toluene Xylenes are important materials for production ofchemicals and petrochemicals In recent years because of an increase in P Xyleneworldwide demand this reaction has a special importance in industrial applications In industrial processes this reaction can be carried out in fixed bed reactors and overacid zeolite catalysts Two major processes that operate basically on this reaction are Tatoray and PX Plus In this work these processes are described and the reactors are modeledmathematically The model results are compared with experimental data reported by otherresearchers and the models are verified Optimization of reactors with mathematical model is another purpose of this workthat is achieved Finally reactors are compared in optimum operational conditions Results of thiscomparison are summarized below For both processes toluene conversion is about 30 5 In PX Plus Process P Xylene Yield is higher than Tatoray Process Para Selectivity for PX Plus process is about 90 In PX Plus process Benzene Xylene molar ratio is higher than tatoray process To achieve optimum conditions PX Plus process needs higher temperature and higher residence time than Tatoray process
