N2 - Hydrothermal liquefaction (HTL) of Litsea cubeba seed was conducted over different temperature (250-350°C), time (30-120min), reactor loading (0.5-4.5g) and Na2CO3 loading (0-10wt.%). Temperature was the most influential factor affecting the yields of product fractions. The highest bio-oil yield of 56.9wt.% was achieved at 290°C, 60min, and reactor loading of 2.5g. The presence of Na2CO3 favored the conversion of the feedstock but suppressed the production of bio-oil. The higher heating values of the bio-oil were estimated at around 40.8MJ/kg. The bio-oil, which mainly consisted of toluene, 1-methyl-2-(1-methylethyl)-benzene, fatty acids, fatty acid amides, and fatty acid esters, had a smaller total acid number than that of the oil obtained from the direct extraction of the starting material. It also contained nitrogen that was far below the bio-oil produced from the HTL of microalgae, making it more suitable for the subsequent refining.
