Fuels and heating oils, a process for their preparation and their use

Claim 2

A fuel for a combustion engine or heating oil comprising a hydrocarbon, water and a non-ionic emulsifier, said non-ionic emulsifier containing less than 1,000 ppm of salt constituents and less than 1 percent by weight of polyalkylene glycol ethers.

Claim 3

A fuel according to claim 1 containing 55 to 97 percent by weight of a hydrocarbon mixture of the type employed in gasoline or diesel oil, 0.5 to 40 percent by weight of water free of anionic salts which form residues, 0 to 30 percent by weight of a monohydric straight-chain or branched C 1 to C 8 -alcohol, 0.5 to 6 percent by weight of a non-ionic emulsifier which has been purified by removing the polyglycol ether constituents and salt constituents, and 0.1 to 4.8 percent by weight of a fatty acid monogylceride, of an adduct of 1-3 mols of ethylene oxide and 1 mol of a fatty acid amide or a mixture thereof, or of a partial ester of a fatty acid and a polyalcohol.

Claim 4

A fuel according to claim 1 wherein said non-ionic emulsifier is an oxyethylation product of an alcohol with 8 to 22 carbon atoms or of an alkyl 1,2-glycol, of a fatty acid, fatty acid amine, fatty amine, synthetic fatty acid, resin acid or naphthenic acid or of an alkylphenol or of an aralkylphenol with 1 to 30 mols of ethylene oxide and/or propylene oxide or of esterification products of fatty acids and glycerol or of a polyalcohol.

Claim 5

A fuel according to claim 1 wherein said non-ionic emulsifier has been purified to remove salt constituents and polyalkylene glycol ether constituents therefrom by dissolving said non-ionic emulsifier in an organic water-immiscible solvent and treating the solution with water, removing the resultant aqueous layer therefrom to leave behind said emulsifier in said organic solvent and removing said organic solvent.

Claim 6

In a process for forming a fuel comprising a hydrocarbon, water and a non-ionic emulsifier wherein said hydrocarbon, water and non-ionic emulsifier are co-mixed the improvement wherein said non-ionic emulsifier is one which contains less than 1,000 ppm of salt constituents and less than 1 percent by weight of polyalkylene glycol ether constituents.

Claim 7

In a process for forming a fuel comprising a hydrocarbon, water and a non-ionic emulsifier wherein said hydrocarbon, water and non-ionic emulsifier are co-mixed the improvement wherein said non-ionic emulsifier is one which contains less than 1,000 ppm of salt constituents and less than 1 percent by weight of polyalkylene glycol ether constituents.

Claim 8

A fuel according to claim 1, wherein said fuel is a fuel for a combustion engine.
