Abstract
A catalyst is provided having higher mercury oxidation performance than a conventional catalyst without increasing catalyst quantity or enhancing SO2 oxidation performance and constitutes an oxidation catalyst for metal mercury, which contains a molybdenum and vanadium complex oxide, for example, MoV2O8, as a main component having a catalytic activity and is formed by placing the molybdenum and vanadium complex oxide in layers only on the surface of a plate-like or honeycomb-like porous carrier. The porous carrier contains Ti and W and has a function of an NOx removal catalyst as a whole.
Claims12
An oxidation catalyst for metal mercury used for oxidatively reacting metal mercury contained in exhaust gas with oxygen or a halogen compound, wherein a main component of the catalyst having a catalytic activity comprises a binary molybdenum and vanadium complex oxide, the molybdenum and vanadium complex oxide being carried in layers only on a surface of a plate-like or a honeycomb-like porous carrier.
