Abstract

PURPOSE: Vanadium oxide catalyst deactivated by the contact with exhaust gas containing NOx and SOx in the presence of NH3 is activated with an aqueous solution containing NH4 + to simply and economically regenerate the catalyst, avoiding the discharge of a large quantity of used catalyst.
