| titleOfInvention | Method of regenerating completely or partially deactivated SCR catalysts and method of using cleaning solutions used in regeneration |
| abstract | The present invention relates to a process for the regeneration of a completely or partially deactivated and calcined SCR catalyst, in particular of the stainless steel grid or honeycomb type containing anatase form of titanium dioxide (TiO2), mixed with active metal oxides: vanadium oxide V2O5, tungsten oxide Mo3 or molybdenum oxide WO3 or , wherein the regenerated SCR catalyst is immersed, preferably completely, in one or separately and in any order in two or three or four multicomponent cleaning solutions having the following composition: solution I containing 0.1-99.7% by weight. CH 3 COOH and / or 0.1 - 99.7 wt. of glycerol, and / or 0.1-99.7% acetone, and / or 0.1-99.7% wt. Na2S2O3; solution II containing 0.1-99.7 wt. CH 3 COOH and / or 0.1 - 99.7 wt. H2SO4, and / or 0.1-99.7 wt. H3PO4, and / or 0.1-99.7 wt. (COOH) 2 · 2H2O; solution III containing 0.1 - 99 wt. NaOH and 1-99.9 wt. H2O2; solution IV containing 0.1-99.9 wt. CH 3 COOH and 0.1 - 99.9 wt. H2O, where the immersion time is at least 30 minutes for each solution I - IV, each immersion step in a certain solution is followed by immersion of the catalyst in water, preferably distilled, for at least 5 minutes, and after completion of the last immersion step of the catalyst in water followed by drying at from 0 to 600 ° C for at least 5 minutes and the cleaning solutions used during regeneration are preferably recycled. |
