Abstract
A method is proposed for the desulphurization of sulphur-containing fuels in which the fuels are mixed with at least one solid basic additive and at least one metal in finely divided form, the mixture thus obtained subjected to a pyrolysis and the sulphur adsorptively or chemically bonded to the basic additive separated by methods known per se. The method is particularly suitable for the desulphurization of heavy fuel oil or used oil, and as solid basic additive preferably lime and as metal preferably iron powder are used. The permanent gas forming in the pyrolysis and the simultaneously forming condensate may be directly fired as low-sulphur fuel.
