ABSTRACT:
A process for reducing nitrogen oxides in the exhaust gas of a combustion device, particularly of an internal-combustion engine, includes melting solid pure urea to obtain a molten product, and adding the molten product to the exhaust gas as the reducing agent for reducing nitrogen oxides. The corresponding device includes a device for the controlled liquefaction of solid pure urea and the injection of the molten product into the exhaust gas.
