Abstract
A regenerating process comprises leaching a combustion ash with water so as to dissolve same and form a pregnant leach liquor containing the additive which is separated from the solid residue. The pregnant leach liquor is thereafter adjusted with a base precipitating agent so as to precipitate a compound of the additive which is then recovered by liquid solid separation. The process of the present invention is particularly useful for regenerating said recycling sulfur capturing additives used in hydrocarbon formulations which are burned as fuels, particularly, hydrocarbon in water emulsions formed from viscous hydrocarbon materials characterized by high sulfur and metals contents.
