Renewable jet-fuel-range alkanes are synthesized by hydrodeoxygenation of lignocellulose-derived high-carbon furylmethanes over ReOx-modified Ir/SiO2 catalysts under mild reaction conditions. Ir?ReOx/SiO2 with a Re/Ir molar ratio of 2:1 exhibits the best performance, achieving a combined alkanes yield of 82–99 % from C12–C15 furylmethanes. The catalyst can be regenerated in three consecutive cycles with only about 12 % loss in the combined alkanes yield. Mechanistically, the furan moieties of furylmethanes undergo simultaneous ring saturation and ring opening to form a mixture of complex oxygenates consisting of saturated furan rings, mono-keto groups, and mono-hydroxy groups. Then, these oxygenates undergo a cascade of hydrogenolysis reactions to alkanes. The high activity of Ir?ReOx/SiO2 arises from a synergy between Ir and ReOx, whereby the acidic sites of partially reduced ReOx activate the C?O bonds of the saturated furans and alcoholic groups while the Ir sites are responsible for hydrogenation with H2.

Diesel range branched alkanes were synthesized by the solvent-free hydrodeoxygenation of 5,5′-(butane-1,1-diyl)bis(2-methylfuran), the hydroxyalkylation/alkylation product of 2-methylfuran and butanal. Over the non-noble metal catalyst Ni/Hβ-(394), ～90% carbon yield of diesel range alkanes was achieved at a much lower temperature (503 K) than the temperature (623 K) used in the literature over noble metal catalysts.
