CATALYST FOR TREATING EXHAUST GASES Russian patent published in 2011 - IPC B01J23/31 B01J21/06 B01J27/192 B01J27/199 B01D53/64 B01D53/56 B01D53/94 

Abstract RU 2429908 C1

FIELD: chemistry.

SUBSTANCE: disclosed is a catalyst for treating exhaust gases on which nitrogen oxide in the exhaust gas is reduced upon getting into contact with ammonia which serves as the reducing agent, and on which mercury is oxidised using a halogen as an oxidising agent, wherein the catalyst contains: TiO2 as a support; at least one oxide selected from a group comprising W, W and Mo oxides, which is deposited onto the support as an active component; and at least one element selected from a group comprising Bi, P and compounds containing Bi and/or P, which is deposited on the support as a catalyst component.

EFFECT: reduced amount of highly corrosive reagent which chlorinates mercury which must be added, high efficiency of oxidising mercury when treating exhaust gases.
