中文摘要	Ru/ZrO/sub 2/-CeO/sub 2/ pelletized catalysts were prepared adopting wet molding method, and the activity survey test of highly concentrated acetic acid and phenol was carried out with acetic acid and phenol as objective. The effects of reaction conditions on COD removal in phenol oxidation process was studied, and catalyst stability was evaluated. Doping Zr into CeO/sub 2/ could enhance the catalyst heat-resistant property. Using wet molding method could lower the roasting temperature. These two could all enhance specific surface area and catalyst activity. The COD removal rate of Ru/ZrO/sub 2/-CeO/sub 2/ in catalytic wet oxidation phenol was raised with the increase of reaction temperature, pressure and catalyst dosage. The optimal reaction conditions were temperature of 150 degrees C; pressure of 3 MPa; catalyst of dosage 35 g/L. In the dynamic experiment of 110 h, COD and phenol removal rates were always above 90%, and the catalyst possessed very high activity and good stability.
