Method and device for providing a gaseous substance mixture |
| abstract |
The device (1) according to the invention for providing a gaseous substance mixture comprising at least one of the following substances:(a) at least one reducing agent and (b) at least one reducing agent precursor, with a -reservoir (20) for an aqueous solution (45) comprising at least one reducing agent precursor being formed, from which reservoir (20) aqueous solution (45) can be delivered into at least one mete-ring line (2) with a dispensing opening (3) by a delivery means (19), is characterized in that means (4) for heating the metering line (2) are formed, by means of which the at least one metering line (2) can be heated above a critical temperature which is greater than the boiling temperature of water. The device (1) according to the invention and the method according to the invention advantageously permit the complete evaporation of an aqueous solution comprising urea, and subsequent hydrolysis to form a substance mixture comprising ammonia. Said substance mixture is advantageously metered as a reducing agent into an SCR catalytic converter (18). The fact that the evaporation is carried out outside the exhaust system permits the formation of considerably smaller hydrolysis catalytic converters (17), so that the device according to the invention is space-saving and cost-saving in comparison with conventional devices for providing a reducing agent for the selective catalytic reduction of nitrogen oxides. |
