Method and system for feeding a reducing agent into a catalyst device

摘要

The present invention concerns a method and a system for feeding a reducing agent into a catalyst device. A first reservoir is provided and has a solid reducing agent, a second reservoir is provided and has a solvent for the solid reducing agent, and a reducing agent solutions is produced from the solid reducing agent and the solvent. The reducing agent solution is intermittently stored in a third reservoir, and the reducing agent solution is fed from the third reservoir into the catalyst device.
