Catalyst and process for nitrogen oxides reduction in combustion exhaust gas

摘要

Disclosed is a method of effectively removing nitrogen oxides contained in exhaust gas from a combustion process with stationary source and mobile source using gases or liquid oils, such as gasoline, kerosene or bio-diesel oil as a fuel. More particularly, there are provided an apparatus and a method of removing nitrogen oxides, in which a reducing agent is sprayed into the exhaust gas passing through an alumina-promoted silver catalyst installed at a flow path of exhaust gas. <IMAGE>
