The present invention is directed to the preparation of oxygenated, unsaturated hydrocarbon compounds, such as derivatives of furfural or hydroxymethyl furfural produced by aldol condensation with a ketone or a ketoester, as well as methods of deoxidatively reducing those compounds with hydrogen under acidic conditions to provide saturated hydrocarbons useful as fuels.

Low chemical stability and high oxygen content limit utilization of the bio‐based platform chemical 5‐(hydroxymethyl)furfural (HMF) in biofuels development. In this work, Lewis‐acid‐catalyzed conversion of renewable 6‐deoxy sugars leading to formation of more stable 5‐methylfurfural (MF) is carried out with high selectivity. Besides its higher stability, MF is a deoxygenated analogue of HMF with increased

properties of NbOx‐based catalysts in the hydrodeoxygenation of furan‐derived adducts to liquidalkanes. Excellent activity and stability were observed with almost no decrease in octane yield (>90 % throughout) in a 256 h time‐on‐stream test. Experimental and theoretical studies showed that NbOx species play the key role in CO bond cleavage. As a multifunctional catalyst, Pd/NbOPO4 plays three roles

We show that 5-(hydroxymethyl) furfural (HMF) and acetone can be selectively converted into a range of biomass-derived high molecular weight chemicals in high yield (>90%). HMF was condensed with acetone and purified to produce HMF-Acetone-HMF dimer (HAH). We then selectively synthesized various compounds from HAH by the sequential catalytic reaction pathway of hydrogenation, ring-opening, and hydrodeoxygenation

We studied the hydrogenation at temperatures from 313–393 K of a biomass-derived platform molecule, 5-hydroxymethylfurfural (HMF)-acetone-HMF (HAH) over Pd, Ru, and Cu based catalysts. HAH was selectively hydrogenated to produce partially-hydrogenated monomers (PHAH) over Cu and Ru catalysts and to fully-hydrogenated HAH monomers (FHAH) over the Ru catalyst. Pd based catalysts yielded a mixture of
