| titleOfInvention | Method and device for providing a reducing agent precursor |
| abstract | The method according to the invention for providing a reducing agent precursor comprises the following steps: A) heating a quasi-closed evaporator volume (3), delimited by a wall (2), which is at least partially filled with a solution (4) of a reducing agent precursor, to a lead temperature of the solution to produce an atmosphere of a steam (7) comprising at least one reducing agent precursor at a lead pressure above the ambient pressure and B) removing, as required, the steam (7) by using the pressure difference between the lead pressure and the ambient pressure. The invention relates to a method and a device (1) for providing reducing agent precursors that can especially be used in the selective catalytic reduction of nitrogen oxides. The method and the device (1) according to the invention allow an easy metering since, owing to the pressure gradient between the steam (7) and the withdrawal line (8), no other conveying means are required when the steam (7) which contains at least one reducing agent precursor is metered to the hydrolytic catalyst (13). |
