Abstract

PURPOSE: To regenerate easily and harmlessly V2O5 by diptreating poisoned V2O5 catalyst in the aqueous solution of alkaline earth element compound etc. and making the sulfuric acid radical of vanadyl compound isoluble and so on, when the poisoned V2O5 catalyst is regenerated.
CONSTITUTION: When poisoned V2 O5 cotalyst is regenerated as a result that, being used for exhaust gas treating, vanadyl compound [(VO2)(NH4)2(SO4)3] is formed with SOx, NH3 etc., poisoned catalyst is diptreated in aqueous solution or slurry of alkaline earth element compound of Mg or Ca etc. (more than one kind of oxides, hydroxides, carbonates, organic salts etc.), and sulfuric acid radical of vanadyl compound is fixed as a isoluble compound, and at the same time the vanadyl radical is oxided to vanadium trioside, being furthermore regonerated to vanadiumto pentoide. This method anables regerate easily and harmlessly even poisoned catalyst due to alkali metal without any loss of vanadium component.
