Abstract Herein we present a high yield 2-methylfuran production process with the required features to be implemented in a future integrated biorefinery. The strategy is based on the right solvent selection, 2-methyltetrahydrofuran, which i) can be used to extract the reactant, furfural, from the aqueous solution obtained after corncob biomass hydrolysis; ii) allows for highly selective 2-methylfuran production form furfural with up to 80% yields and iii) presents suitable biofuel properties in the gasoline range. Using this innovative approach, two energy intensive separation steps are avoided: the initial furfural purification and the final solvent/product complete separation. Further benefits of this process arise from the developed low-cost, selective, and reusable Cu-Co/γ-Al2O3 catalyst.

通过综合生物精炼方法从生物质中生产 2-甲基呋喃

摘要在此，我们提出了一种高产 2-甲基呋喃生产工艺，其具有在未来集成生物精炼厂中实施所需的功能。该策略基于正确的溶剂选择，2-甲基四氢呋喃，i) 可用于从玉米芯生物质水解后获得的水溶液中提取反应物糠醛；ii) 允许以高达 80% 的收率从糠醛生产高选择性 2-甲基呋喃，并且 iii) 在汽油范围内具有合适的生物燃料特性。使用这种创新方法，避免了两个能源密集型分离步骤：最初的糠醛纯化和最终的溶剂/产品完全分离。该工艺的进一步好处来自于开发的低成本、选择性和可重复使用的 Cu-Co/γ-Al2O3 催化剂。
