Claims
- 1. A process for converting urea into ammonia, which comprises:
feeding an aqueous urea solution to a reaction chamber; flowing the aqueous urea solution through a catalytic converter in the reaction chamber and thereby catalytically converting urea into ammonia; introducing additional energy into the reaction chamber by irradiating with microwaves; and discharging an ammonia-water mixture formed in the reaction chamber from the reaction chamber.
- 2. The process according to claim 1, which comprises conducting the aqueous urea solution in the catalytic converter through capillary tubes containing a catalytically active substance.
- 3. The process according to claim 1, which comprises conducting the aqueous urea solution in the catalytic converter through capillary tubes containing a catalytically active substance on an inner surface thereof.
- 4. The process according to claim 1, which comprises introducing the microwaves such that the ammonia evaporates together with water in the reaction chamber.
- 5. The process according to claim 1, which comprises admixing the ammonia-water mixture as a reducing agent for deNOxing with a flue gas, and feeding the mixture to an SCR reactor together with the flue gas.
