In order to find out the research hotspots and development trends of highdensity aviation fuel, the research methods of information visualization and network analysis are adopted, and the papers in the field of high-density aviation fuel research in Web of Science (WoS) from 2009 to 2022 are used as data sources to draw a social network map, and analyze the development trends, research hotspots and frontier trends in the research field. The results show that since 2009, the number of documents issued has shown a significant upward trend. China is the country with the largest number of documents, followed by the United States and the United Kingdom; According to the cooperation of the authors, there are mainly three cooperative groups, among which Zou jijun is the core group with the largest number of papers; The keyword results show that catalytic conversion and hydrodeoxygenation of high-density aviation fuel are the current research focus, and biomass based high-density aviation fuel is the future research focus.

“…Zero‐aromatic, high‐performance jet fuel surrogates prepared from RJ‐4 and various SPKs have recently been studied with RJ‐4 concentrations as high as 50 % [17] . Due to its high density, pure RJ‐4 has applications as a high NHOC fuel for cruise missile propulsion, [38–40] while its low volatility and high flashpoint are well suited for ramjet engines [41] . More recently, researchers have shown that RJ‐4 can be efficiently converted to 1,3‐dimethyladamantane, a thermally stable jet fuel of interest for high speed applications [42] …”

The sustainable, bio-based, platform chemical, 2,5-hexanedione [HD (1)], was efficiently converted to methylcyclopentadiene [MCPD (4)] through a three-step process consisting of intramolecular aldol condensation, catalytic chemoselective hydrogenation, and dehydration. Base-catalyzed aldol condensation of 1 resulted in the formation of 3-methyl-2-cyclopenten-1-one [MCO (2)], which was then converted to 3-methyl-2-cyclopenten-1-ol [MCP (3)] by chemoselective reduction with a ternary Ru catalyst system [RuCl 2 (PPh 3) 3 /NH 2 (CH 2) 2 NH 2 /KOH]. The hydrogenation proceeded with 96 % chemoselectivity. 3 was then dehydrated over AlPO 4 /MgSO 4 at 70°C under reduced pressure to yield 4, which can undergo an ambient temperature [4 + 2]-Diels-Alder cyclization to generate dimethyldicyclopentadiene (DMDCPD), a commodity chemical useful for the preparation of high-performance fuels and polymers. Through this approach, advanced jet fuels and materials can be conveniently produced from sustainable cellulosic feedstocks.

“…Polycyclic hydrocarbon molecules therefore stand out from many molecular types as high energy density molecules. 15 For the adamantanes, it is a kind of centrally symmetric, highly stable, cagelike hydrocarbon whose basic carbon skeleton structure is very similar to the diamond lattice cell structure.

High energy density fuels (HEDFs) that have high volumetric net heat of combustion (NHOC), high stability, and high environmental resistance are greatly important in the fuel field and in military bases and aerospace applications. In this paper, molecular dynamics and quantum chemistry were used to compute the significant physical properties of candidate molecules for HEDFs, such as their enthalpies of combustion, enthalpies of vaporization, densities, and melting points. A computational protocol for evaluating these properties in the fuel field was established, including a new method for estimating the melting point. By using our protocol, we found that, to improve fuel performances such as the density and volumetric NHOC, cyclopropanation is obviously better than hydrogenation. Our protocol was verified to have good accuracy and can be used to compare and assess different target molecules as potential HEDFs.
