Abstract
AbstractCatalytic oxidation of toluene over a series of Pt‐(Sn/Re)‐HZSM‐5/HMS catalysts has been studied at atmospheric pressure and 200–500°C temperature. The results show when the Sn and Re were incorporated into the catalysts, a clear improvement in catalytic activity could be observed in toluene oxidation. The key process parameters including temperature, time on stream, and Sn/Re weight ratio were optimized by response surface methodology integrated central composite design. The suggested optimization model showed satisfactory correlation between the predicted and actual results. The temperature was the most significant parameter affecting on the toluene conversion and CO2 selectivity, whereas Sn/Re ratio is another effective parameter.
