ABSTRACT:
The invention relates to a method for regenerating denox catalysts having an increased SO2/SO3conversion rate as a result of the cumulation of iron compounds, and is characterized in that the catalysts are treated with an essentially aqueous acid solution, preferably having a pH between 0.5 and 4, and with an addition of antioxidants.
