摘要

Mesua ferrea Linn (MFL) is an evergreen flowering tree in the family Clusiaceae and mainly grown in South Asia and Southeast Asia, particularly Sri Lanka, India, and Myanmar. MFL seeds have high oil content ranging from 75 to 80% by weight. In this work, MFL seed oil was hydroprocessed in a 2-liter batch reactor at 400 °C and 5 bar initial H2 pressure using biomass wastes supported Ni/Mo and commercial Pd/C catalysts for one hour. Catalytic hydroprocessing produced about 92% biocrude that was distilled using a True Boiling Point (TBP) distillation unit in accordance with ASTM D2892 and ASTM D5236 specifications. On volume basis, the green gasoline (35–140 °C) fraction was found to be 6–10%, the green kerosene/aviation fuel (140–180 °C) of 5–7%, and the green diesel (180–370 °C) fraction of 33–35%, in addition to 7–9% of the wax (370–482 °C). The total distillates recovery from TBP distillation unit was 51–65% of the original biocrude. The density for gasoline fraction varies in the range 0.74–0.76 g cc− 1, 0.82–84 g cc− 1 for kerosene fraction and 0.83–0.85 g cc− 1 for diesel fraction. In contrast, kinematic viscosity for gasoline fraction (0.64 cSt) is slightly higher than that of petro-gasoline (0.37–0.44 cSt). However, kinematic viscosity for kerosene fraction (0.93 cSt) is very close to petro-kerosene (1-5.2 cSt) and it falls within the acceptable range for diesel fraction (2.8 cSt). Moreover, higher heating values and flash points for distillate fractions vary in between 40 and 45 MJ kg− 1 and 36–80 °C respectively. The observed fuel properties of most of the distillate’s fractions were comparable to petroleum counterparts, indicating that they could be used as an equivalent substitute for petro-fuels.
