Bio-oil from Fast Pyrolysis of Forage Sorghum Biomass

The objectives of this research are to: 1) Characterize the chemical composition and physical and thermal properties of forage sorghum biomass related to pyrolysis processing; 2) Develop a coordinated understanding of the relationship among composition, physical and thermal properties, processing condition, and bio-oil yield; 3) Determine the optimum pyrolysis conditions for high bio-oil yield and low energy input. The chemical, physical and thermal properties of forage sorghum biomass will be correlated to bio-oil yield and composition of bio-oil. Pyrolysis will be carried out in a bench-scale fast pyrolysis auger reactor. The main reaction parameters such as reaction temperature, feed rate (residence time), and particle size of biomass feedstock will be optimized for high bio-oil yield and low energy input. Each portion of the fractions from pyrolysis including gas, bio-oil, and char will be collected and analyzed separately. Bio-oil from pyrolysis of biomass has the similar properties as petroleum oil. The bio-oil can be converted to hydrocarbon fuels including "green" gasoline, diesel and jet fuel by utilizing the same refining technologies applied to petroleum and coal-liquid conversion. Forage sorghum has a similar chemical composition as corn stover and should be an excellent feedstock for bio-oil production. However, no research has been done on pyrolysis of forage sorghum, even there are no scientific information about thermal properties of forage sorghum available. The main milestones of this research will include developing a coordinated understanding of the relationship among composition, physical and thermal properties, processing condition and bio-oil yield; and determine the optimum pyrolysis conditions for high bio-oil yield and low energy input.
