Title:
SYSTEM USING SELECTIVE CATALYTIC REDUCTION FOR IMPROVING LOW-TEMPERATURE DE-NOX EFFICIENCY AND REDUCING YELLOW PLUME
Document Type and Number:
WIPO Patent Application WO/2012/064025
Kind Code:
A3
Abstract:
The present invention relates to a method for removing nitrogen oxides (NOx) more effectively at 300°C or less using a selective catalytic reduction (SCR) technique in boilers, incinerators, diesel engines, glass melting furnaces, and the like. To this end, by mounting an oxidation catalyst in front of an NOx-reducing device employing a conventional SCR technique and by adjusting the NOx composition ratio, i.e. the ratio of NO to NO2, to 1:1 in the exhaust gas, a de-NOx catalytic reaction is carried out under optimized fast-SCR conditions, thereby maximizing low-temperature de-NOx efficiency.
