Abstract

PURPOSE:To provide the title catalyst which shows high activity even at low temps. and is used for selective catalystic reduction in the prescense of NH3 by dipping steel the surface layer of which has been alloyed with Al in an Al sol. soln. to elute Al and treating the peroforated surface layer with a SO2-contg. gas after which a V cpd. is supported.
