Regenerating catalyst, used for removing nitrogen oxides from waste gas produced by gas turbine, involves passing regeneration gas from waste gas of drive unit having combustion engine through catalyst
Process for regenerating a SCONOx-catalyst (6) for removing NOx from waste gas produced by a gas turbine (1) involves passing regeneration gas containing molecular hydrogen or hydrocarbons through the catalyst, the gas originating from the waste gas of a drive unit having a combustion engine. An Independent claim is also included for a device for carrying out the process comprising a SCONOx-catalyst for removing NOx; a line (8) for the regeneration gas; and a drive unit (7) containing a combustion engine having an exhaust outlet connected to the line. Preferred Features: The waste gas from the drive unit used to prepare the regeneration gas is passed through a steam reforming catalyst (11) to convert the carbon monoxide and steam to carbon dioxide and molecular hydrogen. The drive unit is operated with a fuel, preferably natural gas, gasoline or propane.
