Simulation of gas phase Catalytic Oxidation of Benzene on Pt/Al2O3 catalytic monolith using CFD

Gas phase Catalytic Oxidation of Benzene as one of VOCs on Pt/Al2O3 catalytic monolith was simulated using CFD. The Catalytic conversion occurs over the monolith catalyst surfaces. The geometry of monolith catalyst was designed in Gambit software and fluent6.2 was applied for simulation of catalytic oxidation process. The experimental conditions were applied for this simulation. It was assumed that there is an isothermal condition across the catalyst bed and a consistent heating profile. A Mixture of gaseous species containing Benzene (1298 ppm, mol/mol) and oxygen (12724 ppm, mol/mol) and containing argon and helium as career gas was considered as inlet feed to reactor. The excellence agreement was obtained between simulation and experiments. The mole fractions of reactants and products along catalyst bed were simulated. Furthermore temperature distribution and surface deposition rate profiles of oxygen during catalyst oxidation were predicted using CFD. This study confirms technique can be considered as a useful tool to study catalytic oxidation of VOC
