Catalytic 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.

Sn和Re促进的Pt@HZSM-5/HMS微/中孔对甲苯全氧化的RSM催化性能优化

已经在大气压和 200–500°C 的温度下研究了一系列 Pt-(Sn/Re)-HZSM-5/HMS 催化剂对甲苯的催化氧化。结果表明，当将 Sn 和 Re 掺入催化剂中时，在甲苯氧化中可以观察到催化活性的明显提高。通过响应面法集成中心复合设计优化了关键工艺参数，包括温度、运行时间和 Sn/Re 重量比。建议的优化模型在预测结果和实际结果之间显示出令人满意的相关性。温度是影响甲苯转化率和CO ₂选择性的最重要参数，而Sn/Re 比是另一个有效参数。
