    • Alternative fuel compositions, blends of the alternative fuel compositions and gasoline, and methods for their preparation and use are disclosed. The alternative fuel compositions ideally include ethanol, isopropyl alcohol, and one or more of sec-butanol and t-butanol, and ideally include no more than 3% methanol, and no more than 15% C5 or higher alcohols. The fuel compositions can be prepared using Fischer-Tropsch synthesis to convert syngas to a product stream comprising C2-4 olefins, and hydrolyzing these olefins. The process facilitates isolation of C2-4 alkanes, because the boiling point difference of these alkanes is significantly lower than that of the C2-4 alcohols. Ideally, the compositions provide more energy per unit volume than E85, even without the addition of gasoline, although the compositions can be blended with gasoline in any desired ratio. The resulting alternative fuel can be derived, at least in part, from renewable resources, in that the syngas can be derived from renewable resources, and a significant portion of the molecule is derived from the water used to hydrolyze the olefins. The alternative fuel compositions, and blends thereof with gasoline, can help reduce U.S. dependence on foreign crude oil.

    • The invention relates to an agent for increasing the octane number of a gasoline automobile fuel, which agent is a combination of alcohol and a product of reaction between a carbonyl compound and a compound containing at least two hydroxyl groups allowing the formation of cycles with carbonyl compounds, or is the mixtures of the above mentioned products. In a preferred embodiment, mono- or oligosaccharides or diatomic, triatomic or polyatomic alcohols are used as the compounds containing at least two hydroxyl groups allowing the formation of cycles with carbonyl compounds. Pentoses, preferably xylose or arabinose or hexose, substantially glucose, and the mixtures thereof are used as the monosaccharides. Glycols, for example, ethylene glycol are used as diatomic alcohols, glycerin is used as triatomic alcohols and erythritols, for example, pentaerythritol are used as polyatomic alcohols. A compound relating to lower aldehydes or lower ketones, for example, formaldehyde, acetaldehyde, acetone, methylethylketone, diethylketone or cyclohexane, is used as a carbonyl compound. The alcohols correspond to aliphatic alcohols containing up to five carbon atoms, preferably ethanol. The inventive gasoline automobile fuel means a gasoline or an alcohol-gasoline composition.
