METHODS FOR REMOVING IRON MATERIAL FROM A CATALYTIC CONVERTER USING AN AQUEOUS ALKALINE SOLUTION AND AN ANTIOXIDANT

摘要

Methods of removing iron from a catalytic converter having an accumulation of one or more iron compounds and regenerating a catalytic converter are provided. A catalytic converter having an accumulation of one or more iron compounds embedded or deposited thereon can be treated with a substantially aqueous alkaline solution in which the substantially aqueous alkaline solution includes an antioxidant.
