For the first time, renewable high density aviation fuels were synthesized at high overall yield (95.6%) by the Guerbet reaction of cyclopentanol which can be derived from lignocellulose, followed by the hydrodeoxygenation (HDO). The solvent-free Guerbet reaction of cyclopentanol was carried out under the co-catalysis of solid bases and Raney metals. Among the investigated catalyst systems, the combinations of magnesium-aluminium hydrotalcite (MgAl-HT) and Raney Ni (or Raney Co) exhibited the best performances. Over them, high carbon yield (96.7%) of C10 and C15 oxygenates was achieved. The Guerbet reaction products were further hydrodeoxygenated to bi(cyclopentane) and tri(cyclopentane) over a series of Ni catalysts. These alkanes have high densities (0.86 g mL(-1) and 0.91 g mL(-1)) and can be used as high density aviation fuels or additives to bio-jet fuel. Among the investigated HDO catalysts, the 35 wt.% Ni-SiO2-DP prepared by deposition-precipitation method exhibited the highest activity.
首次通过环戊醇的盖布瑞尔反应（Guerbet反应）以高总产率（95.6%）合成了可再生高密度航空燃料，环戊醇可从木质纤维素中获得，随后进行加氢脱氧（HDO）。环戊醇的无溶剂盖布瑞尔反应在固体碱和雷尼金属的共催化下进行。在所研究的催化剂体系中，镁铝水滑石（MgAl-HT）与雷尼镍（或雷尼钴）的组合表现出最佳性能。在它们之上，实现了C10和C15含氧化合物的高碳产率（96.7%）。盖布瑞尔反应产物在一系列镍催化剂上进一步加氢脱氧生成二环戊烷和三环戊烷。这些烷烃具有高密度（0.86 g mL⁻¹和0.91 g mL⁻¹），可作为高密度航空燃料或生物喷气燃料的添加剂。在所研究的加氢脱氧催化剂中，通过沉积沉淀法制备的35 wt.% Ni-SiO₂-DP表现出最高活性。
