Considering the global carbon emissions and ambition of carbon neutrality, renewable fuels synthesized from biomass have great application prospects. Herein we adopted hydrogenation and cyclopropanation to synthesize four biofuels using α-cedrene and longifolene as feedstocks. Specifically, the modified Simmons-Smith method was used to synthesize cyclopropanation biofuels with a yield greater than 80% under the optimized conditions. The as-prepared biofuels possess the density of 0.925-0.965 g/mL, and the volumetric energy of 39.45-41.51 MJ/L. Additionally, the minimum ignition temperature and ignition delay time of the synthesized biofuels are shortened by 46-108 °C and 27.0-71.4%, respectively, compared with the widely used JP-10 fuel. The synthesized sesquiterpene-based biofuels have good potential to as alternative of high energy density fossil fuels like JP-10.
