摘要：
A method for reactivating noble metal-containing zeolites containing sulfur oxide poisoned noble metal such as oxygen regenerated platinum zeolite beta catalysts, by contacting the catalyst with an acidic aqueous solution having a pH below about 7. The solution contains a Bronsted acid compound having a dissociation constant ranging from about 1.times.10.sup.-14 to about 2.times.10.sup.-1.
