deNOx deNOx DENOX CATALYST WITH IMPROVED NITROGEN OXIDE REDUCTION PERFORMANCE AT HIGH TEMPERATURE METHOD FOR PRODUCING THE SAME AND DENOX SYSTEM USING THE SAME

摘要

An object of the present invention is to provide a CO-SCR catalyst excellent in reducing nitrogen oxides at high temperature. In addition, it is an object of the present invention to provide a CO-SCR catalyst that has an excellent ability to reduce nitrogen oxides without using a noble metal-based active phase and thus has an effect of cost reduction. The deNOx catalyst with improved nitrogen oxide reduction performance at high temperatures according to the present invention is a catalyst for reducing nitrogen oxides (NOx) using carbon monoxide (CO) in exhaust gas as a reducing agent, and includes a support on which barium (Ba) is supported. It is characterized.
