Abstract

There is provided a catalyst that exhibits a high denitration efficiency at a relatively low temperature and does not cause oxidation of SOin a selective catalytic reduction reaction that uses ammonia as a reducing agent. A denitration catalyst molded in a block shape contains 43 wt % or more of vanadium pentoxide. The denitration catalyst has a BET specific surface area of 30 m/g or more and is used for denitration at 200° C. or lower.
