Abstract
Bio-oil, a liquid product obtained from pyrolysis of solid biomass, can be used as a sustainable feedstock for the production of renewable fuels and chemicals. Sawdust was used as the feedstock for obtaining bio-oil in conical spouted bed reactor through fast pyrolysis. Liquid-liquid extraction method was used to separate the bio-oil into different chemical groups by their polarities to stabilize bio-oil and improve the quality. Similar oxygen-containing functional groups were present in water and solvent phase of the separated bio-oil. Chloroform, hexane, and petroleum ether were used for the extraction of chemicals from the sawdust bio-oil through liquid-liquid extraction. The solvent phase had high concentrations of organic compounds. With chloroform extraction solvent, 65.89%(w) of organics in water phase were extracted.
