  • Combustion improvers for normally liquid fuels
    Publication number: 20040093790
    Abstract: Fuel compositions comprising a major amount of a normally liquid fuel and a minor amount of a hydroxylamine or a salt thereof, more often wherein each hydroxylamino group of the hydroxylamine or salt thereof contains no more than one tertiary alkyl substituent. The hydroxylamine or salt thereof provide improved combustion properties to a wide variety of normally liquid fuels, including hydrocarbon based fuels, oxygenates and synthetic fuels.
