This study focuses on developing a new class of high energy density (HED) bio-aviation fuel. Alkyl bicyclo[2.2.2]octanes (ABCOs) were designed as potential HED aviation fuel, and a C₁₂ ABCOs mixture was synthesized from renewable resources (α-phellandrene and maleic anhydride) using the Diels–Alder cycloaddition followed by hydrotreating. The synthesized ABCOs exhibited favorable fuel properties as HED fuel, including a gravimetric net heat of combustion comparable to Jet A-1 and higher density and volumetric net heat of combustion. ABCOs standalone showed poor low-temperature viscosities than Jet A-1 specifications but demonstrated no freezing behaviors even at extremely low temperatures. Fuel properties after blending ABCOs with Jet-A1 were also investigated, determining an upper limit of blending ratio of 44.1 vol%. These findings suggest that ABCOs can serve as a promising drop-in fuel for conventional jet fuel, while also potentially contributing to the formulation of bio-based and zero-aromatic high-performance jet fuels as a density-increasing component.

这项研究的重点是开发一种新型高能量密度（HED）生物航空燃料。烷基双环[2.2.2]辛烷（ABCO）被设计为潜在的HED航空燃料，并使用Diels-Alder环加成和加氢处理从可再生资源（ α-水芹烯和马来酸酐）合成C _{12 ABCO混合物。}合成的 ABCO 作为 HED 燃料表现出良好的燃料特性，包括与 Jet A-1 相当的重量净燃烧热以及更高的密度和体积净燃烧热。ABCO 单独表现出比 Jet A-1 规格差的低温粘度，但即使在极低的温度下也没有表现出冻结行为。还研究了 ABCO 与 Jet-A1 混合后的燃料特性，确定混合比例的上限为 44.1 vol%。这些研究结果表明，ABCO 可以作为传统喷气燃料的一种有前途的替代燃料，同时也有可能有助于生物基和零芳香族高性能喷气燃料的配方作为密度增加的成分。
