Enhanced multi step solvent extraction for fractionated bio oil production from sugarcane bagasse via hydrothermal liquefaction

Multi-step hydrothermal liquefaction and solvent extraction of sugarcane bagasse was able to improve the quality and recovery of bio-oil. THF was the best solvent to use in the extraction and longer reaction time and increased temperature favored more yield and deoxygenation. Hydrothermal liquefaction is one of the feasible and viable thermal aptitude transformation methods that can be used to convert sugarcane bagasse into renewable biofuels and chemical intermediates. The end products of the bio-oils were found to be combustible with similar properties compared to the petroleum crude oil.
