摘要： 考察了不同制备方法和不同活性组分的催化剂在微波场中（150℃，4 MPa）湿式催化氧化处理苯酚模拟废水（COD_Cr为22 000 mg/L）的效果。结果表明，涂覆法制备催化剂的活性和稳定性均优于浸渍法制备催化剂。Ru（0.25%）-Fe-Ce/Al₂O₃-堇青石催化剂的性能最佳，反应40 min后对COD_Cr去除率达到93.5%，连续反应10次后去除率未明显降低。

Abstract: The wet catalytic oxidation effects of catalysts prepared by different methods and different active components in amicrowave field(150℃,4 MPa) on the phenol simulated wastewater(COD_Cr is 22 000 mg/L) have been investigated. The results show that the catalytic activity and stability of the catalyst prepared by the coating method are superior to the catalyst prepared by the impregnation method. The catalytic capability of the Ru(0.25%)-Fe-Ce/Al₂O₃-cordieritecatalyst is optimal. After reacted for 40 min,the COD_Cr removing rate reaches 93.5%,and no obvious decrease appears after reacted 10 times continuously.

Key words: high concentration phenol wastewater, wet catalytic oxidation, catalytic activity, microwave field
