ABSTRACT OF THE DISCLOSURE The present invention relates to a catalyst to be used for catalytically reducing nitrogen oxides contained in a com- bustion exhaust gas discharged from a calcination furnace, a coking furnace or a boiler or an exhaust gas from a nitric acid- preparing plant in the presence of a reducing gas such as ammonia to convert the nitrogen oxides to harmless substances, and to a method for converting these nitrogen oxides by using this catalyst. According to the present invention, in the presence of a catalyst consisting essentially of oxides or organic or inorganic compounds of V and Nb or V, Nb and at least one element selected from the group consisting of Cu, Ti, Fe, Cr, W, Mo and Ni, which are supported on a carrier, a reducing gas such as ammonia is incorporated in an exhaust gas, and nitrogen oxides in the exhaust gas are catalytically reduced and converted to harmless substances. The catalyst of the present invention is not deactivated by other components contained in the exhaust gas, such as sulfurous acid gas, water and the like, and a very high conversion of nitrogen oxides can be attained not only in the high temperature range but also in the low temperature range.
