Abstract

The synthesis of high-quality fuels from biomass-derived platform chemicals is challenging. Herein, Ru/WO₃–ZrO₂ (Ru/xWZ, where x is the wt% of WO₃) catalysts with varying WO₃ loadings were synthesized and explored for the hydrodeoxygenation (HDO) of biomass-derived furfural-acetone aldol adducts (FAc) to alkanes. Notably, WO₃ loadings had a marked effect on the catalytic HDO of FAc to alkanes. Complete FAc conversion with a 95% yield of alkanes (octane : heptane – 82 : 18) was achieved over the Ru/5WZ catalyst under optimized reaction conditions (150 °C, 2 MPa H₂, and 3 h). Control experiments and NH₃-TPD and HR-TEM results inferred that the optimum loading of WO₃ is crucial for tuning the acidic sites and the exposure of the Ru surface sites in the Ru/xWZ catalysts to achieve high catalytic activity for the HDO of FAc to alkanes.

在 Ru/WO3-ZrO2 催化剂上将生物质衍生呋喃加氢脱氧成液态烷烃

从生物质衍生的平台化学品合成高质量燃料具有挑战性。在此，我们合成了不同 WO3 负载的 Ru/WO3-ZrO2（Ru/xWZ，其中 x 为 WO3 的重量百分比）催化剂，并探索了将生物质衍生的糠醛-丙酮醛醇加合物（FAc）加氢脱氧生成（HDO）为烷烃的方法。值得注意的是，WO3 负载对 FAc 到烷烃的催化 HDO 有显著影响。在优化的反应条件下（150 °C，2 兆帕 H2，3 小时），Ru/5WZ 催化剂实现了 FAc 的完全转化，烷烃（辛烷：庚烷 - 82:18）收率达到 95%。对照实验、NH3-TPD 和 HR-TEM 结果表明，WO3 的最佳负载量对于调整 Ru/xWZ 催化剂中的酸性位点和 Ru 表面位点的暴露至关重要，从而实现将 FAc HDO 转化为烷烃的高催化活性。
