Catalytically converting nitrogen oxide in exhaust gas stream mixed with ammonia to form water and nitrogen comprises feeding gas stream together with added catalytically active substance to reaction chamber

摘要

Catalytically converting a nitrogen oxide in an exhaust gas stream mixed with ammonia to form water and nitrogen comprises feeding the gas stream (A) together with an added catalytically active substance (S) to a reaction chamber (2). Independent claims are also included for the following: (a) a process for reacting a catalyst module (3) produced by depositing a catalytically active material in or on a catalyst substrate (31) comprising wetting the catalyst module with a catalytically active substance; (b) a fuel for burning in a combustion process containing the catalytically active substance; and (c) an exhaust gas purification device for a power station or a vehicle combustion engine comprising an injection device for injecting the catalytically active substance into the fuel.
