Abstract
PURPOSE:In reducing and removing of nitrogen oxides in exhaust gases by NH3 the nitrogen oxides are safely and efficiently removed over a long period of time by using the catalysts which have high poisening resistance to sulfur oxides, high reduction activity, good mechanical strength and moldability.
