Abstract
45 kinds of catalysts belonging to 3 series were prepared by solid phase calcination. These catalysts were used in treating butyric acid wastewater by microwave catalytic oxidation process, and COD removal rate was used as an indicator to evaluate effects of catalysts. The preparation process was optimized with orthogonal experiments and the preferred was characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). Results indicated that the Ni-Co-Ce-O was the best catalyst( Ni: Co = 1:1, NiO + Co2O3/CeO2 = 1 :4). The optimal preparation conditions were: Ni: Co molar ratio of 1:2, (NiO + Co2O3)/CeO2 mass ratio of 5％ , grinding time of 40 min, calcination temperature of 450 ℃ and calcination time of 3 hours. Under these conditions, catalytic efficiency was highest and about 67％ of COD removal rate could be obtained.关键词
