英文摘要: In this paper, copper-based catalysts for the catalytic wet air oxidation of organic wastewater were prepared. The catalysts and their precursors were analyzed by XRD, XRF and TG-DTG. It was found that there is no or little Cu leaching for Cu-Al-Zn catalyst whose precursor possesses hydrotalcite-like structure. In the degradation of phenol, sodium dodecyl-benzenesulfonate and sulfosalicylic acid under the reaction condition of initial oxygen pressure 0.5 MPa and temperature 160similar to220 degreesC, Cu leaching is below 0.3 mg/L. The preliminary theory calculation and analysis for the stability of the catalysts were made.
