Desulfurization and denitrification performance of M-Y/AC catalysts

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.
