Abstract
Method of preparing monolithic SCR catalyst with a plurality of gas flow channels comprising the steps of (a) providing a monolithic shaped substrate with a plurality of parallel gas flow channels; (b) coating the substrate with a wash coat slurry comprising vanadium oxide precursor compounds and titania and optionally tungsten oxide precursor compounds; and (c) drying the thus coated substrate with a drying rate of 5 mm/min or less along flow direction through the gas flow channels; and (d) activating the dried coated substrate by calcining.
