  • 摘要: 采用等体积浸渍法制备Fe/γ-Al2O3催化剂，以500 mg·L-1间甲酚为模型化合物评价催化剂的活性及稳定性.考察了反应温度、初始pH、过氧化氢投加量和催化剂焙烧温度对催化剂催化活性和稳定性的影响.结果表明：350℃焙烧的Fe/γ-Al2O3催化剂，在3.0 g·L-1催化剂投加量，60℃反应温度，H2O2理论投加量，初始pH值为4.0，反应2 h的条件下，间甲酚转化率及TOC去除率分别达到99.9%和58.6%.考察了多相、均相催化剂在反应中的作用，结果表明Fe/γ-Al2O3的多相催化在反应过程中起主要作用.
    Abstract: Catalysts were prepared with incipient wetness impregnation method and tested by catalytic wet hydrogen peroxide oxidation (CWPO) of m-cresol model wastewater. The effect of operating conditions were investigated, namely reaction temperature, initial pH, hydrogen peroxide concentration and catalyst calcination temperature. Working at 60℃, an initial pH of 4.0, 500 mg·L-1 of m-cresol, a dose of H2O2 corresponding to the stoichiometric amount and 3.0 g·L-1 of Fe/γ-Al2O3 catalyst which was calcined at 350℃,99.9% m-cresol conversion, 58.6% TOC removal efficiency were achieved. Heterogeneous catalysis contributed more than homogeneous catalysis on degradation of m-cresol wastewater in CWPO process.
