Abstract

The following invention presents a method of removing pollutants from purifying catalyst of flue gas treatment system, wherein said catalyst comprising inter alia manganese free-metal oxides, metalosilicates or any mixture thereof. The method comprises admixing effective measure of solution comprising up to 50% basic agents and/or oxidants so that reusable salts and oxides are obtained. The catalyst for removing SOx, NOx and/or mercury form purifying catalyst of flue gas treatment system comprising inter alia metal oxide, metalosilictaes or any mixture thereof.
