Towards transportation fuel production from food waste: Potential of biocrude oil distillates for gasoline, diesel, and jet fuel

Biocrude oil from hydrothermal liquefaction (HTL) demonstrates promise as a supplement to the transportation fuel supply. However, its poor chemical (heteroatom content, energy content), physical (viscosity, density), and thermal (boiling point distribution, cetane value, cold-flow properties) characteristics limit commercial application. This study investigated potential for biocrude distillates derived mobile, pilot-scale HTL conversion of food waste serve (gasoline, diesel, jet fuel) blendstock. Distillation increased H:C (4.2–13.7%), decreased O:C (5.5–93.5%), N:C (6.0–39.0%), augmented HHV (4.1–21.3%) compared oil, leading values 1.97, 0.003, 0.004, 52.0 MJ•kg?1, respectively. These were similar (1.65, 1.94, 2.02), (0.02, ~0, ~0), (0.0002, 0.002, 0.002), (50.0, 53.1, 53.4 MJ•kg?1) gasoline, Jet A fuels, With respect properties, distillation density (23.8–30.5%) viscosity (99.5–99.9%), while acidity either or depending on temperature. Despite benefits distillation, blending is still required due N:C, viscosity, distillates. Theoretical calculations determined that with was most favorable blendstock, amounting deviations 63.3–316.6% when distillate proportion ranged 10 50%.
