Abstract:
1. A combined cycle power generation facility comprising a catalyst configuration for removing nitrogen oxides in exhaust gas by reduction in the presence of ammonia, wherein the mole ratio of NO 2 /NO in the exhaust gas is 1 or greater, wherein the catalyst configuration comprises a first catalyst and a second catalyst, wherein: the first catalyst of the catalyst configuration is for removing nitrogen dioxide and comprises at least one oxide selected from the group consisting of copper oxides and chromium oxides; the second catalyst of the catalyst configuration is for removing nitrogen monoxide and comprises a titanium oxide and at least one oxide selected from the group consisting of vanadium oxides, tungsten oxides and molybdenum oxides; and the first catalyst of the catalyst configuration is arranged on the upstream side in the exhaust gas flow direction of the second catalyst of the catalyst configuration.
