CATALYST FOR REDUCTION OF NITROGEN OXIDE AND OXIDATION OF MERCURY IN EXHAUST GAS AND METHOD FOR REMOVING NITROGEN OXIDE AND MERCURY SIMULTANEOUSLY USING THE CATALYST

摘要

PURPOSE: A catalyst for reduction of nitrogen oxide and oxidation of mercury in exhaust gas and a method for removing nitrogen oxide and mercury simultaneously using the catalyst is provided to a nitride oxidation reduction effect corresponding to the existing SCR catalyst and simultaneously remove the nitride oxidation and mercury. CONSTITUTION: A catalyst for reduction of nitrogen oxide and oxidation of mercury in exhaust gas removes a nitride oxide from an exhaust gas through selective catalytic reduction, and a transition metal halide is dipped on the surface of the catalyst. The selective reduction catalyst includes a vanadium pentroxide dipped on the titanium dioxide supporter. A method for removing nitrogen oxide and mercury simultaneously using the catalyst comprises the steps of: removing a nitride oxide from an exhaust gas by injecting a reduction material into a catalyst reaction container in which the transition metal halide is dipped on the selective oxidation catalyst and oxidizing mercury into an oxidation mercury by supplying a halogen nitrogen; and removing the oxide mercury.
