  • Exhaust gas aftertreatment
    Patent number: 11619157
    Abstract: A method for exhaust gas aftertreatment is provided, the method comprising: a) providing a nitrogen oxide-containing raw exhaust gas, b) introducing the nitrogen oxide-containing raw exhaust gas into a catalytic evaporator (1), c) introducing a urea solution and a fuel into the catalytic evaporator (1), as a result of which a reducing agent is obtained, and d) supplying the reducing agent to an exhaust gas aftertreatment system (8). Alternatively or in addition, a device for producing a reducing agent may be provided, a reducing agent produced with same, and the use of these objects.
