Abstract

PURPOSE: To prevent arsenic oxide from being deposited and to maintain the denitrating action at a long period by preparing both a catalytic active component and titania by means of a coprecipitating method in a catalyst for denitrating flue gas contg. nitrogen oxide.
CONSTITUTION: A flue gas denitration catalyst is obtained by preparing both catalytic active components and titania by means of a coprecipitating method. In this case, as the catalytic active components, active metal such as Sn, Cu, Co, Fe, Cr and Ni having highly active denitration performance is used. The amount of oxide of the above-mentioned metal to be incorporated is preferably a value within the range of 0.2W40wt% for a TiO2 carrier. The obtained catalyst has an amorphous state wherein the active metal is uniformly dispersed in all parts of the catalyst and is stable. Further since the active metallic oxide forms a stable composite oxide together with titania, the join of both arsenic oxide incorporated in flue gas and dust, and the active metal is prevented thereby the nitrating action can be maintained a long time.
