Abstract (en)

The method envisages the involvement of any industrial mixer (8) to which an aqueous solution (1) of an oxoacid of the chalcogens with an oxoacid of the pnictogens and an aromatic sulfonic acid or mixtures (2) thereof are added and they are mixed with the heavy fraction (3) or hydrocarbon residue to be treated, such that this mixture is heated by way of any conventional heating system (9) to a temperature comprised between 20 and 100°C and once the reaction is carried out, the resulting product is forced to pass to a decanter or centrifuge machine where the separation step (4) of the organic phase (5) from the aqueous phase (6) takes place. An organic phase used directly as a fuel (7) which contains at least 0.5% by weight of polymeric solids and the viscosity thereof is below 100 mm 2 /s at 50°C is thereby obtained.
