Bio-tar production by liquefaction of Kraft lignin in super- and subcritical solvents |
| 초록 |
Lignin which is one of three major components consisting of lignocellulosic biomass is generated about 7 million ton annually from pulping mills. Recently lignin has received high attention as a source for the production of energy and/or value-added chemicals. Among the technologies under development, liquefaction is considered the most favorite route for the production of high quality biofuel or valuable chemicals from technical lignins like Kraft lignin. In this work, lignin residue obtained from a Kraft pulping process was used for production of bio-tar that can be used as a precursor for carbon fiber via bio-pitch formation. The effect of liquefaction parameters such as temperature, reaction time and kind of solvent on the conversion of lignin in super- and subcritical solvents was investigated. The characterization of liquefaction products was also carried out by GC, GC-MS, TGA, proximate, and ultimate Analyses. |
