Abstract

PURPOSE: A highly durable NOx cleaning catalyst resistant to water and sulfur oxide is provided by using water-insoluble vanadyl sulfate and titanium dioxide.
CONSTITUTION: Pentavalent vanadium compound such as ammonium metavanadate, vanadium pentaoxide is mixed with ammonium sulfate and titanium oxide in the presence of water and then dried. Alternatively titanium oxide is impregrated with vanadium compound and ammonium sulfate and then dried. The dried product is fired at 250 to 400°C in an atmopsphere containing either signle sulfur oxide or a mixture of sulfur oxide and ammonia. This results in a water insoluble product consisting of vanadyl sulfate and titanium dioxide. The resultant product is used as NOx cleaning catalyst, providing excellent resistivity to water and sulfur oxide, long period durability, and low temperature activity. An a further advantage, the catalyst can be easily regenerated by washing with water.
