Abstract (en)
[origin: WO02094420A1] The invention relates to a method for carrying out the selective catalytic reduction of nitrogen oxides with ammonia in the lean exhaust gas of a combustion process executed using a first lean air/fuel mixture. According to the invention, the ammonia required for the selective reduction is obtained from a second rich air/fuel mixture, which contains nitrogen monoxide, by reducing the nitrogen monoxide in a NH>3< synthesis stage to ammonia while forming a product gas stream. The ammonia produced thereby is separated out from the product gas stream and is stored in a storage medium for the requirement-orientated use during the selective catalytic reduction.
