Fuel comprising an emulsion between water and a liquid hydrocarbon, said emulsion being stabilized by adding a polymeric surfactant obtainable by reaction between: (i) a polyolefin oligomer functionalized with at least one group deriving from a dicarboxylic acid, or a derivative thereof; and (ii) a polyoxyalkylene comprising linear oxyalkylene units, said polyoxyalkylene being linked to a long-chain alkyl group optionally containing one or more ethylenic unsaturations. The fuel has high stability over time, without forming carbonaceous deposits which adhere to metal surfaces.
Cette invention a trait à un combustible contenant une émulsion eau hydrocarbure liquide, laquelle émulsion est stabilisée par adjonction d'un tensioactif polymère pouvant être obtenu grâce à une réaction entre, (i), un oligomère polyoléfinique fonctionnalisé par au moins un groupe issu d'un acide dicarboxylique ou son dérivé et, (ii), un polyoxyalkylène possédant des motifs oxyalkylènes linéaires, ledit polyoxyalkylène étant lié à un groupe alkyle à longue chaîne contenant, éventuellement, une ou plusieurs insaturations éthyléniques. Ce combustible, qui est très stable dans le temps, ne forme pas de dépôts carbonés adhérant à des surfaces métalliques.
