Method for the desulphurization of sulphur-containing fuels and fuel desulphurized by the method
A method is described for desulphurization of sulphur containing fuels selected from the group consisting of heavy fuel oil, used oil, and mixtures thereof, comprising mixing the fuel with: At least one solid basic additive selected from the group consisting of carbonate, hydrogen carbonate, hydroxides of alkali metals, hydroxides of alkaline earth metals, aluminium hydroxide, oxides of alkaline earth metals and aluminium oxide, employed in finely divided form; and At least one elemental metal in finely divided form selected from the group consisting of Mg, Ca, Fe, Co, Ni, ZN, Cd, Al, Sn and Pd. The metal is present in greater amount than the basic additive. Subjecting the mixture so formed to pyrolysis at a temperature between 500/sup 0/ and 1200/sup 0/C produces hydrogen which reduces elemental sulphur and sulphur containing compounds to hydrogen sulphide, whereby the fuel yields a permanent gas portion, a condensate portion and a residue portion containing the reduced sulphur while the permanent gas portion and condensate portion are substantially sulphur free, and removing the residue sulphur containing portion from the condensate portion and the permanent gas portion.
