Abstract

The hydrogenation of biomass-derived molecules is a key reaction in upgrading these compounds into chemicals and fuels. The use of catalytic transfer hydrogenation, employing alcohols as hydrogen sources, offers an alternative approach to this process, avoiding the use of H2 under high pressure and precious metal catalysts. In this work, the gas-phase conversion of biomass-derived furfural into furfuryl alcohol and 2-methylfuran was studied, using methanol as the H-transfer agent and CaO-based catalysts. The results obtained with this catalyst were compared with those obtained by using MgO, which due to its basic properties and to its high surface area, at present appears to be among the best basic catalysts used for the conversion of biomass-derived molecules. Pure CaO, despite having a very low surface area, compared to MgO catalyst (5 m2/g vs. 172 m2/g), was shown to reduce furfural into its corresponding unsaturated alcohol at 350°C, thus allowing selective H-transfer from methanol to the substrate. These results highlight the potential application of the H-transfer reaction over CaO based catalysts as an efficient process for the selective reduction of biomass-derived molecules.
