ABSTRACT A method is described for the ecological recovery of carbonaceous substances, usable in particular as so- lid fuels, from acid sludge originating from the treat- ment of petroleum fractions with sulphuric acid. According to the present invention, the acid sludge is removed from its deposits in the form of pieces of any size, and is simultaneously neutralised surperficially and partially by means of basic powdered solids and/or liquids, followed by complete neutralisation under stir- ring, and cooling to a temperature of between 35 and 150°C, in oder to obtain solid fuels. The neutralising agents used are calcium salts and va- rious other inorganic or organic basic materials.
