Liquid transportation fuels must burn cleanly and have high energy densities, criteria that are currently fulfilled by petroleum, a non-renewable resource, the combustion of which leads to increasing levels of atmospheric CO2, An attractive approach for the production of transportation fuels from renewable biomass resources is to convert carbohydrates into olkanes with targeted molecular weights, such as C-8-C-15 for jet-fuel applications. Targeted n-alkones can be produced directly from fructose by an in-tegrated process involving first the dehydration of this Q sugar to form 5-hydroxymethylfurfural, followed by controlled formation of C-C bonds with acetone to form C, and C,5 compounds, and completed by hydrogenation and hydrodeoxygenation reactions to form the corresponding n-alkanes. Analogous reactions are demonstrated starting with 5-methylfurfural or 2-furoldehyde, with the latter leading to C, and C, n-alkanes.
