Abstract
A process is described for reducing the levels of nitrogen oxides present in flue gases from stationary sources. The process consists of mixing ammonia or methane with the flue gas and then passing the mixtures through a bed of expanded vermiculite, the latter serving as a catalyst for reactions between the nitorgen oxides and ammonia or methane. The reactions result in the formation of nitrogen and water and/or carbon dioxide.
