Catalytic reduction of SO2 with CH4 to elemental sulfur: A comparative analysis of alumina, copper-alumina and nickel-alumina catalysts
The catalytic reduction of sulfur dioxide with methane to form elemental sulfur has been studied. Al2O3, Cu-Al2O3 and Ni-Al2O3 were examined as catalysts and their performances were compared in terms of SO2 conversion and selectivity. Performance of the catalyst extremely enhanced when nickel and copper were added as promoters. The effects of temperature, SO2/CH4 molar ratio, and reaction...
متن کاملOptimization and Modeling of CuOx/OMWNT’s for Catalytic Reduction of Nitrogen Oxides by Response Surface Methodology
A series of copper oxide (CuOx) catalysts supported by oxidized multi-walled carbon nanotubes (OMWNT’s) were prepared by the wet impregnation method for the low temperature (200 °C) selective catalytic reduction of nitrogen oxides (NOx) using NH3 as a reductant agent in the presence of excess oxygen. These catalysts were characterized by FTIR, XRD, SEM-EDS, and H2-TPR meth...

Low Temperature Selective Catalytic Reduction Using Molding Catalysts Mn-Ce/FA and Mn-Ce/FA-30%TiO2
Mn-Ce/FA (M) and Mn-Ce/FA-TiO2 (M), using fly ash (FA) with and without TiO2 as the carriers, were prepared by an integral molding technique. With the increase of TiO2 content, the rates of NO conversion and denitration of Mn-Ce/FA-TiO2 (M) increased, and the NO2 and N2O formation rates decreased. It is found that TiO2 could effectively inhibit the excessive oxidation of NO and the generation o...
