摘　　要：对CuO-CeO2/AC(活性炭载氧化铜和氧化铈)吸附-催化剂低温干法催化氧化所吸附苯酚的行为进行了研究.结果表明,CeO2的引入促进了CuO/AC对吸附苯酚的低温催化氧化活性,苯酚初始催化氧化温度降低约30℃;连续吸附-催化氧化循环过程中的苯酚吸附量平均提高6%左右,苯酚脱附量平均减少77%.铈掺杂的促进作用可能在于提高了表面化学吸附态的氧含量,进而减少了催化氧化过程中在吸附-催化剂表面形成的残留物量.An activated carbon （AC） supported copper and cerium oxide adsorption catalyst （CuO-CeO2/AC） was studied for catalytic dry oxidation of adsorbed phenol at low temperatures. The results show that the addition of CeO2 to CuO/AC significantly promotes its catalytic activity for phenol oxidation. The initial oxidation temperature of the adsorbed phenol is lowered by 30 ℃, the phenol adsorption capacity is increased by about 6%, the desorption of phenol in oxidation is reduced by about 77% and the residues formed in the oxidation are reduced. The effect of CeO2 on the process would be attributed to its oxygen that can be used for oxidation of phenol.
