Abstract
PURPOSE: To regenerate V - TiO2 catalyst deactivated in denitration of exhaust gas contg. SOx and dust with no deformation by washing the catalyst with water and contacting it with an aq. soln. of oxallic acid of a specified concn. to extract part of the V component after which a V cpd. is supported and calcined.
