羟烷基化与加氢脱氧相结合是合成可再生优质柴油或喷气燃料的一条很有前途的路线。本文首次将一系列固体酸催化剂用于木质纤维素呋喃与羰基化合物的HAA反应。在所研究的催化剂中，Nafion-212树脂表现出最高的活性和稳定性。2-甲基呋喃（2-MF）与糠醛的HAA反应具有较高的反应活性和工业集成化的优势，是一条具有应用前景的路线。催化剂用量、反应温度和反应时间对2-MF和糠醛在Nafion-212树脂上的HAA有明显影响。最后，2-MF和糠醛的HAA产物在Pd/C催化剂上加氢和在Pt负载的固体酸催化剂上加氢脱氧。Pt/磷酸锆（Pt/ZrP）是最佳的加氢脱氧催化剂。超过4% Pt/ZrP催化剂，94？%柴油和75%的碳产率实现了C15烃（以6-丁基十一烷作为主要组分）的碳产率。
Hydroxyalkylationalkylation (HAA) coupled with hydrodeoxygenation is a promising route for the synthesis of renewable high-quality diesel or jet fuel. In this work, a series of solid-acid catalysts were firstly used for HAA between lignocellulose-derived furan and carbonyl compounds. Among the investigated catalysts, Nafion-212 resin demonstrated the highest activity and stability. Owing to the high activity of the reactants and the advantage in industrial integration, the HAA of 2-methylfuran (2-MF) and furfural can be considered as a prospective route in future applications. Catalyst loading, reaction temperature, and time had evident effects on the HAA of 2-MF and furfural over Nafion-212 resin. Finally, the HAA product of 2-MF and furfural was hydrogenated over a Pd/C catalyst and hydrodeoxygenated over Pt-loaded solid-acid catalysts. Pt/zirconium phosphate (Pt/ZrP) was found to be the best catalyst for hydrodeoxygenation. Over the 4?% Pt/ZrP catalyst, a 94?% carbon yield of diesel and 75?% carbon yield of C15 hydrocarbons (with 6-butylundecane as the major component) was achieved.
