Patent ID: 8288309

Claim:
A mercury oxidation catalyst for oxidizing mercury in an exhaust gas into a water-soluble mercury compound, the mercury oxidation catalyst comprising: TiO 2 as a carrier; V 2 O 5 and MoO 3 supported on the carrier as active components; at least one kind of element or compound selected from the group consisting of W, Cu, Co, Ni, Zn, or the compounds thereof supported on the carrier as a MoO 3 volatilization preventing component; and, the mercury oxidation catalyst being formed by, preparing a catalyst material solution A containing the MoO 3 to serve as a first active component and the MoO 3 volatilization preventing component; supporting catalyst components in the catalyst material solution A on a substrate containing the TiO 2 carrier; drying and calcining the substrate having been subjected to the step of supporting catalyst components in the catalyst material solution A; preparing a catalyst material solution B containing the V 2 O 5 to serve as a second active component; supporting catalyst component in the catalyst material solution B on the carrier having been calcined previously; and drying and calcining the carrier having been subjected to the step of supporting catalyst component in the catalyst material solution B on the carrier.
