In this study, bio-oil was produced from sugarcane bagasse through fast pyrolysis process, and the phenolic compounds in the bio-oil were extracted. The bio-oil produced at 500 degrees C and 700 degrees C showed properties closer to diesel fuel, and the optimal conditions for phenolic compounds extraction were found to be 40 degrees C and 250 rpm.
In the current study, bio-oil was produced from sugarcane bagasse via fast pyrolysis process. The process was conducted at 500 degrees C and 700 degrees C using a heating rate of 10 degrees C/s. The values of density, viscosity, acid number, flash point, and heating value of bio-oil produced from pyrolysis of sugarcane bagasse at 700 degrees C were closer to that of diesel fuel compared to bio-oil produced at 500 degrees C. The major components of the bio-oil produced from biomass pyrolysis are phenolic compounds. The total phenolic compounds content in the bio-oil prepared via sugarcane bagasse pyrolysis at 500 degrees C and 700 degrees C were approximately 48.43 and 58.89%, respectively. These phenolic compounds could decrease the quality of bio-oil. Therefore, in this study, the phenolic compounds contained in the bio-oil produced were extracted by using a mixture of methanol and chloroform for 50 min at temperatures of 25, 40, and 50 degrees C with stirring speeds of 200, 250, and 300 rpm. Additionally, Folin-Ciocalteu method was employed to determine the phenolic compounds amount in the bio-oil. The chemical composition and physical properties of the bio-oil were also determined. The main chemical components of the bio-oil produced were phenol and furfural. The optimum conditions for phenolic compounds extraction were found at 40 degrees C and 250 rpm. The highest yields of phenol and distribution coefficients were found to be 58.89% and 1.504 for fast pyrolysis at 500 degrees C and 48.43% and 1.528 at 700 degrees C.
