Abstract

PURPOSE: To provide the title catalyst with superior low temp. activity which scarcely suffers a lowering in activity due to ammonium sulfate type by-products, and is easily regenerated by heating.
CONSTITUTION: The catalyst for denitration by an ammonia reduction method consists of TiO2; 2W99%, V2O5; 0.5W50%, and oxides of Y or lanthanides; 0.1W50%. A titanium-contg. cpd. such as titanic acid, titanium chloride or ilmenite, a vanadium cpd. such as vanadyl sulfate, and a cpd. contg. yttrium or various lanthanides are mixed in a predetermined ratio, kneaded with a binder such as dextrin or ammonium stearate, and press or extrusion molded. In case the cpds. are supported, a soln. of the above mixt. is impregnated into carrier made of heat resistant material molded into a predetermined shape. The above molded product or impregnated carrier is then calcined at 350W450°C to convert each of the components into oxide.
