Lignin is generated as a byproduct in pulping process and bio-ethanol production process. Currently most of lignin byproduct is used to provide process heat by combustion. Lignin can also be used to produce liquid fuels or value-added chemicals via thermochemical processes such as high-pressure liquefaction, pyrolysis, and gasification. In this work, possibility for the production of liquid fuels by liquefaction of hydrolysis lignin was experimentally investigated in supercritical ethanol. KOH was used as a catalyst because of its low cost and high catalytic ability to produce hydrogen from supercritical ethanol. Hydrogen is required to conduct deoxygenation reactions, resulting in the production of liquid fuel with high heating value. The effect of temperature, initial gas, and reaction time on the yield and heating value of liquid fuel was studied. |
