Abstract

PURPOSE: To obtain a highly active long life catalyst, as the catalyst of an ammonia reducing method of nitrogen oxide, by using Sn oxide, V oxide and oxide of W, Mo or the like.
CONSTITUTION: As a catalyst composition for catalytically reducing nitrogen oxide in a gas in the presence of ammonia, Sn oxide, V oxide and oxide of W, Mo or the like are contained. This catalyst composition can reduce and remove nitrogen oxide effectively over a long period of time even if oxygen, a sulfur compound and/or moisture are present.
