Production of high quality fuels from lignocellulose-derived chemicals: a convenient C-C bond formation of furfural, 5-methylfurfural and aromatic aldehyde

A new route of converting the whole of lignocellulose biomass derived molecules into high quality fuels was developed with C-C bond formation as the key step. The fuel precursors with 10-14 carbons could be easily obtained though direct self-coupling of furfural, 5-methyfurfural or aromatic aldehyde, the main components of lignocellulose, under mild conditions in water. After dehydration/hydrogenation, straight or branched alkanes with 8-14 carbons within diesel ranged fuels were obtained in moderate to high yield.
