Abstract
An exhaust gas treatment catalyst for removal of one or more pollutants in an exhaust gas, the catalyst comprising: a SO3-reducing catalyst powder which removes the above-described pollutants; and a diluent powder which is not the SO3-reducing catalyst powder nor a catalyst for reactions between exhaust gas components and a reagent, wherein the SO3-reducing catalyst powder is dispersed in the diluent powder.
Claims11
An exhaust gas treatment catalyst for removal of one or more pollutants in an exhaust gas containing NOX and SO3, the catalyst comprising:
- a catalytic powder which removes NOX and SO3;
- and
