Abstract
A method for introducing at least one gaseous reducing agent for a nitrogen oxide into a gas mixture, and a device for carrying out the method. Thermal energy is supplied to a body made from a starting material of the reducing agent, so as to form the reducing agent. The starting material used is urea. The reducing agent formed is ammonia. This method is used in particular to reduce nitrogen oxides in the exhaust gas from internal-combustion engines.
