摘要
The invention relates to a method for producing a gaseous reducing agent for use in the reduction of nitrogen oxides in oxygen-containing exhaust gases, especially in the exhaust gases of internal combustion engines, that are subjected to a selective-catalytic post-treatment in a catalyst. The inventive method is characterized by contacting a solid reducing agent with a liquid heat-transfer agent that is heated to a heating temperature that lies in the range of the evaporation temperature of the reducing agent.
