ABSTRACT:
Fuel made from an emulsion between water and a liquid hydrocarbon and polymeric surfactant, used to stabilize the emulsion, obtainable by (a) reacting (i) at least one polyolefin oligomer functionalized with at least one group deriving from a dicarboxylic acid, or a derivative thereof; and (ii) at least one polyoxylalkylene having linear oxyalkylene units, the polyoxyalkylene being linked to a long-chain alkyl group optionally containing at least one ethylenic unsaturation; and (b) reacting the product of step (a) with (ii) at least one nitrogen compound selected from monoamines, polyamines and quaternary ammonium hydroxides. The fuel has high stability over time, without forming carbonaceous deposits adhering to metal surfaces.
