Low temperature regeneration method of sulfate-deactivated scr catalysts using no2 injection |
| abstract |
The present invention provides a method for the removal of ammonium bisulfate and/or ammonium sulfate from a selective catalytic reduction converter in a combustion facility, wherein the selective catalytic reduction converter is selected from substrates coated and/or impregnated with a selective catalytic reduction catalyst, extruded SCR converters and SCR plate catalyst, and wherein the combustion facility comprises means for measuring the relative activity of the NO<sub>x</sub> conversion of the selective catalytic reduction converter and/or the NH<sub>3</sub> slip concentration. The method comprises the steps of passing flue gas through a converter for the selective catalytic reduction of nitrogen oxides in the presence of ammonia added to the flue gas either as such or in the form of a precursor thereof, injecting a gas containing nitrogen dioxide into the flue gas upstream of the converter for selective catalytic reduction at a flue gas temperature of between 150 and 330°C, wherein the gas containing nitrogen dioxide is added in an amount that keeps the relative activity of the selective reduction catalyst at a value of higher than or equal to 40 %, or wherein the gas containing nitrogen dioxide is added in an amount that keeps the NH<sub>3</sub> slip below 20 ppm NH<sub>3</sub>. |
