| titleOfInvention | Regeneration method of denitration catalyst |
| abstract | PURPOSE: To regenerate the titled catalyst till the level equal to unused catalyst by washing tungsten-titania denitration catalyst wherein SO 2 oxidizing performance has been risen with an aq. oxalic acid soln., thereafter impregnating tungsten comps. therein, depositing said comps. thereon, drying and calcining said catalyst. n CONSTITUTION: In case of regeneration of spent tungsten-titania denitration catalyst wherein SO 2 oxidizing performance has been risen due to adhesion or accumulation of dust components, after said spent denitration catalyst is washed with an aq. oxalic acid soln. of 0.1W5.0wt% concn. of oxalic acid for 30W120min, tungsten compsn. are impregnated therein and deposited thereon by the method such as said catalyst is immersed in an aq. ammonium paratungstate soln. or the like and the catalyst is dired and calcined. As a result, the tungsten-titania catalyst wherein SO 2 oxidizing performance has been raised can be regenerated till the level equal to unused catalyst without damaging the shape. n COPYRIGHT: (C)1985,JPO&Japio |
