Low-temperature CO reduction denitration V/AC catalyst and preparation method and application thereof

The invention relates to a low-temperature CO reduction denitration V/AC catalyst and a preparation method and application thereof, which belong to the technical field of flue gas purification. The preparation method comprises the following steps of adding cocoanut active charcoal particles into a nitric acid solution for activation to obtain an AC carrier, adding the AC carrier into a VOSO4 solution for impregnation, and roasting at 450-550 DEG C in a nitrogen atmosphere to obtain the low-temperature CO reduction denitration V/AC catalyst. The low-temperature CO reduction denitration V/AC catalyst can be used as a low-temperature catalyst, CO is used as a reducing agent to remove NOx in flue gas, the preparation method of the low-temperature CO reduction denitration V/AC catalyst is simple, the dispersity of vanadium oxide is good, and the low-temperature CO reduction denitration V/AC catalyst has the advantages of being high in denitration rate, good in nitrogen selectivity and the like. 本发明涉及一种低温CO还原脱硝V/AC
