NITROGEN OXIDE REDUCTION CATALYST USING MULTI-STAGE SPRAYING AND ITS APPLICATION

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method capable of removing nitrogen oxide contained in an exhaust gas by arranging a catalyst to remove nitrogen oxide contained in the exhaust gas discharged from the burning process of fixed and moving discharge sources and a catalyst which supports silver on an alumina carrier at a travel path of the exhaust gas and spraying a reducing agent at the front edge of the installed catalyst.

SOLUTION: This invention is a method for effectively reducing nitrogen oxide contained in the exhaust gas discharged from the burning process of the fixed and moving exhaust sources whose fuel is a liquid oil such as gas or a gas oil, kerosene and bio-diesel oil. And in further details, this is an apparatus and method for nitrogen oxide treatment by arranging the catalyst which supports silver on an alumina carrier at a travel path of the exhaust gas and then spraying a reducing agent at the front edge of the installed catalyst.
