ABSTRACT:
A process for removal of sulfur from fossil fuels, such as coal, lignite, peat and fuel oil. The process includes the oxidative treatment of the fuel at or about ambient temperature, followed by a wash with a dilute basic aqueous solution of a basic compound of alkali metal or alkaline earth metal at or about ambient temperature. Upon burning of the fuel, a large amount of the sulfur is trapped as a sulfate in the resulting ash rather than as a gas in the effluent.
