제목 Liquefaction of technical lignins in a continuous reactor
초록 Lignin is the largest renewable source of naturally obtainable aromatic hydrocarbons; the efficient utilization of which has been acknowledged as the most logical alternative to the depleting fossil fuels. Owing to its notorious nature of structural complexity and being chemically recalcitrant, its processing has been proven quite challenging indeed. Therefore, much of the scientific research, for its conversion into valuable bio-based chemicals or fuels, has been limited to the lab-scale batch reactors. In this work, we investigated depolymerization of technical lignins in sub- and supercritical solvents using a continuous reactor. The concentrated sulfuric acid hydrolysis and Kraft lignin, with high lignin-to-solvent ratio (up to 30 wt%) were used as reactants. The reactor was designed to hold the pressure up to 350 bars at 400 °C and equipped with a continuously stirred feeder. The liquid and gas products were periodically collected and analyzed.
