Abstract

This study highlights the effectiveness of hydrodeoxygenation (HDO) in converting lignin oils from Eucalyptus, Poplar, and Pine wood, derived from reductive catalytic fractionation (RCF), into renewable cycloalkanes for jet fuel. Using a low-cost Ni₂P/SiO₂ catalyst, the process achieved yields of 91 %, 84 %, and 75 % of renewable cycloalkanes respectively. In addition, the process exhibited high selectivity towards a specific range of hydrocarbons mostly present in aviation fuel (C₉ to C₁₅), with values of 70 %, 60 % and 62 % for the three feedstocks, respectively, showcasing the potential for high-value fuel production. The research underscores the importance of modifying lignin oil properties through various chemo-catalytic biorefining pathways, which significantly influence the quality of the produced blend via HDO. These findings provide valuable insights into optimizing feedstock characteristics for improved jet-range hydrocarbon production.

最佳木质素油——可持续航空燃料（SAF）中替代环烷烃的最佳原料。

本研究强调了加氢脱氧（HDO）将还原催化分馏（RCF）提取的桉树、杨树和松木中的木质素油转化为可再生的航空燃料环烷烃的有效性。采用低成本Ni2P/SiO2催化剂，再生环烷烃的产率分别为91%、83%和75%。此外，该工艺对主要存在于航空燃料中的特定范围的碳氢化合物（C9至C15）具有高选择性，三种原料的选择性分别为70%，60%和62%，显示出高价值燃料生产的潜力。该研究强调了通过各种化学催化生物精炼途径修饰木质素油性质的重要性，这将显著影响通过HDO生产的混合物的质量。这些发现为优化原料特性以提高喷气范围内的油气产量提供了有价值的见解。
