--- MANGANESE-CERIA-TUNGSTEN-TITANIA CATALYST FOR REMOVING NOX AT LOW TEMPERATURE AND PREPARING METHOD SAME

摘要

A manganese-based catalyst exhibiting excellent nitrogen oxide (NOx) removal activity in a low temperature region of 200 ° C or lower and having durability against hydrogen fluoride, a method for producing the same, and a method for removing nitrogen oxide using the catalyst. The present invention relates to a method for preparing a catalyst for removing nitrogen oxides by supporting an active material containing manganese and ceria on a titania carrier, which comprises the step of adding tungsten to control the oxidation of manganese and ceria Ceria-tungsten-titania catalyst for removing nitrogen oxides.
