2‐Methylfuran (MF) is a candidate to be a high‐quality fuel additive. For the first time, efficient Co‐Cu/ZrO₂ catalysts were prepared by the sol‐gel method and herein used for MF synthesis from furfural. Although a 9.2% MF yield and no MF was obtained using Cu/ZrO₂ and Co/ZrO₂, respectively, a 77.5% MF yield was observed at 200°C, under 1.5 MPa initial H₂ pressure for 4 hours using a Co‐Cu/ZrO₂ catalyst. The Co amount was changed in the catalyst structure and the effect of the Co amount on furfural hydrogenation was investigated. The most effective catalyst was the Co‐Cu/ZrO₂ catalyst, with 0.08 g/g (8 mass%) Cu and 0.118 g/g (11.8 mass%) Co. The activity tests of the catalysts were carried out for hydrogenation of furfural to MF by changing reaction parameters such as pressure, loading of catalyst, temperature, and time. A 94.1% MF yield was achieved in the presence of the Co‐Cu/ZrO₂ catalyst with 0.08 g/g (8 mass%) Cu and 0.118 g/g (11.8 mass%) Co at 200°C for 6 hours under 1.5 MPa H₂ pressure. The catalyst also showed good reusability properties after the fifth use. The catalysts were characterized by Brunauer‐Emmet‐Teller method, X‐ray diffraction, X‐ray photoelectron spectroscopy, and temperature programmed reduction techniques.

高效溶胶凝胶铜钴/氧化锆催化糠醛加氢制2-甲基呋喃

2-甲基呋喃（MF）是高品质燃料添加剂的候选者。首次通过溶胶-凝胶法制备了高效的Co-Cu / ZrO ₂催化剂，并用于糠醛的MF合成。尽管使用Cu / ZrO ₂和Co / ZrO ₂分别获得9.2％的MF收率和没有MF的结果，但是在200°C，1.5 H2初始H ₂压力下使用Co / ZrO _{2的情况下}，在200°C下观察到77.5％的MF收率。 Cu / ZrO ₂催化剂。改变了催化剂结构中的钴含量，研究了钴含量对糠醛加氢的影响。最有效的催化剂是Co-Cu / ZrO ₂含0.08 g / g（8质量％）的Cu和0.118 g / g（11.8质量％）的Co.催化剂。通过改变反应参数（如压力，负载量）将糠醛氢化为MF进行了催化剂活性测试。催化剂，温度和时间。在Co-Cu / ZrO ₂催化剂与0.08 g / g（8质量％）的Cu和0.118 g / g（11.8质量％）的Co的存在下，在200°C下于1.5的条件下进行6小时，MF收率达到94.1％MPa H ₂压力。在第五次使用后，该催化剂还显示出良好的可重复使用性。通过Brunauer-Emmet-Teller方法，X射线衍射，X射线光电子能谱和程序升温还原技术对催化剂进行了表征。
