| description | A method for desulfating a nitric oxide (NO) adsorber in an exhaust gas purification apparatus for a combustion unit compris operating the combustion unit so the exhaust gas composition oscillates between rich and lean during the desulfating process, th excess oxygen during the lean periods being collected in a reservoir downstream of the NO adsorber for release during the rich periods to oxidize sulfur compounds. An Independent claim is also included for an exhaust gas purification apparatus for a combustion unit, comprising a NO adsorber, means for establishing an oscillating rich and lean exhaust gas composition during the desulfating process, and an oxygen reserv downstream of the NO adsorber. |
