#CMT# #/CMT# The method involves contacting an exhaust gas flow with an oxidation catalyst that comprises a catalytically active species with iron doping zeolite, where change of temperature of the exhaust gas stream is less than 1 Kelvin/minute. A temperature of the exhaust gas is provided between 380 degree Celsius and 450 degree Celsius, where content of oxygen in the exhaust gas lies between 8 to 12 percent. An output of 1000 kilo watt is produced by a stationary engine. A catalyst carrier and a coating are provided in the catalyst. #CMT# : #/CMT# An independent claim is also included for a device comprising an exhaust gas cleaning system. #CMT#USE : #/CMT# Method for cleaning exhaust gas flow from meagerly operated stationary engine in a motor vehicle. #CMT#ADVANTAGE : #/CMT# The method reduces concentration of nitrogen oxides and laughing gas for reducing carbon monoxide and hydrocarbon emission in the stationary engine and simplifies exhaust gas cleaning process. #CMT#INORGANIC CHEMISTRY : #/CMT# The catalyst comprise metallic oxide selected form aluminum oxide, silicon oxide, ferric oxide, cerium oxide, and zirconium oxide. #CMT#METALLURGY : #/CMT# The oxidation catalyst comprises palladium, platinum, rhodium, iridium, silver, gold, or metallic oxides of iron, manganese and copper. |
