<p>Novel fuels consisting of emulsions of water in hydrocarbons (e.g. diesel fuel) are disclosed. The underlying problem is that of providing fuels (e.g. for engines) consisting of stable, non-polluting, low-cost water/hydrocarbon emulsions. The solution provided consists of an emulsion of water in at least one hydrocarbon, said emulsion including a surfactant system that essentially comprises a sorbitan sesquioleate (I), a polyethylene glycol monooleate (II) and a nonylphenol ethoxylate (III), characterised in that the average droplet size of the aqueous dispersed phase is no higher than 1 νm, with a standard deviation of 1 νm, and in that the emulsifying system composition is I:II:III → 3:2:1 parts by weight. The surfactant system has an HLB from 6 to 8. A method for preparing said emulsions is also disclosed. The fuels may be used as diesel oil, petrol, kerosene or fuel oil optionally emulsified with water.</p> |
