2015年2月25日 · Hydrodeoxygenation (HDO) of furfurals, which are produced from the dehydration of the sugars, in particular, is a key step in many of the reaction pathways proposed for the upgrading of cellulosic biomass into value-added fuels and chemicals.

Furfural (FUL) is substantially produced by the polymeric xylan fraction of hemicellulose with the presence of acids, and 2-methyl furan (2-MF) produced from FUL is an important biogasoline additive. Here, we report that 2-MF can be selectively formed from FUL with a 90% yield at 220 °C within 2 h over Cu 0 /Cu 2 O·SiO 2 sites via a copper ...

2024年6月1日 · Hydrodeoxygenation of furfural over non-noble metal catalyst is an effective route to synthesis 2-methylfuran, but the reaction is often hampered by the low activity and selectivity of the catalyst.

STM reveals the formation of hydrogen-bonded networks for planar furfural, which favor decarbonylation on clean Pt (111) and hydrogenolysis in the presence of coadsorbed hydrogen. Preadsorbed hydrogen promotes furfural hydrogenation to furfuryl alcohol and its subsequent hydrogenolysis to methyl furan, while suppressing residual surface carbon.

2025年1月15日 · The catalytic performance for furfural hydrodeoxygenation to 2-methylfuran of the CuPd/Al 2 O 3 catalysts, using isopropanol as a hydrogen donor, shows a volcano-type relationship to the Cu/Pd ratio. The highest 2-methylfuran yield (81% at 220 °C) was achieved on the single atom alloy catalyst Cu 8 Pd 1 /Al 2 O 3 .

2022年5月15日 · In this work, a thorough experimental and computational study of furfural hydrogenation, deoxygenation, and ring opening reactions over various catalysts (Ni/C, Pd/C, Pt/C, Cu/C, Ru/C, Rh/C, Re/C) was conducted, by using tetrahydrofuran as a solvent and gaseous hydrogen as hydrogenation agent.

2014年4月22日 · Your MoMo so cat, she splits furfural: Molybdenum carbide (Mo 2 C) is identified as a highly selective deoxygenation catalyst for making 2-methylfuran from furfural through combination of density functional theory (DFT) calculations, surface science and …

Our experimental results clearly demonstrate that the nature of iron oxide is critical in the efficient hydrodeoxygenation of furfural to methyl furan and provides insights toward the rational design of catalysts toward C–O bonds’ hydrodeoxygenation in the production of fuel components.

Vapor phase hydrodeoxygenation (HDO) of furfural over Mo 2 C catalysts at low temperatures (423 K) and ambient pressure showed high/low selectivity to C O bond/C–C bond cleavage, resulting in selectivity to 2-methylfuran (2MF) and furan of ~50–60% and <1%, respectively.

2017年4月4日 · STM reveals the formation of hydrogen-bonded networks for planar furfural, which favor decarbonylation on clean Pt (111) and hydrogenolysis in the presence of coadsorbed hydrogen. Preadsorbed hydrogen promotes furfural hydrogenation to furfuryl alcohol and its subsequent hydrogenolysis to methyl furan, while suppressing residual surface carbon.
