ABSTRACT:
The process and the device are provided for the selective catalytic reduction of nitrogen oxides in an oxygen-containing gaseous medium. The reducing agent required for the reaction is prepared in a separate preparation reactor. A substance that can be converted into the reducing agent is introduced into a carrier gas in the preparation reactor and, as a result, is converted by substantially thermal conversion. The energy required for the conversion is provided by the carrier gas.
