Abstract

PURPOSE: To carry out the decomposition of nitrogen oxides by reducing with NH3 while maintaining the catalyst activity very effectively and over a long period of time even in the coexistence of SOx, by using the carrier consisting of calcium silicate as the main component after having been treated with sulfuric acid, as the catalyst carrier.
