M-Y/AC催化剂同时脱硫脱硝性能研究

摘要: 采用等体积浸渍法制备了一系列的1%M-6%Y/AC（M为Ni、Al、Mo）催化剂，以CO作为还原剂，考察其同时脱硫脱硝的催化活性，通过X射线衍射（XRD）、H₂-程序升温还原（H₂-TPR）、比表面积（BET）对催化剂进行表征。活性评价结果表明，1%Ni-6%Y/AC催化剂的脱硫脱硝催化活性最佳，无氧条件下SO₂和NO的t₉₀分别为383和378℃。在考察NiO的负载量对催化剂影响中，0.5%Ni-6%Y/AC催化活性最佳，无氧条件下SO₂和NO的t₉₀分别为370和360℃。

Abstract: The catalysts M-Y/AC were prepared by incipient-wetness impregnation method and characterized by XRD, H₂-TPR and BET analysis. The experiments of simultaneous removal for SO₂ and NO over M-Y/AC catalyst were conducted in a fixed bed reactor using CO as reducing gas. Ni-Y/AC catalyst shows an excellent desulfurization and denitration performance. As the catalyst is loaded with 0.5% of Ni and 6% of Y, the t₉₀ of SO₂ and NO removal in the absence of oxygen is 370℃ and 360℃, respectively.
