Abstract:
A V2O5-based catalyst for removing nitrogen oxides, comprising vanadium pentoxide and one of barium oxide and calcium oxide as active components loaded on a titanium dioxide support, said titanium dioxide support being prepared by sufficiently drying and calcining a metatitanate (TiO(OH)2)-predominating slurry obtained from production of titanium dioxide for pigment from ilmenite, and said vanadium pentoxide being loaded at an amount of about 1.0 weight % to about 10 weight % based on a total weight of the catalyst provided that the amount of vanadium pentoxide loaded on said titanium dioxide support does not exceed approximately 0.145 gram per square meter of a specific surface area of said titanium dioxide support.
