Lignin, which represents almost 30 wt% of lignocellulosic biomass, is an abundant bioresource which can produce aromatic compounds due to its natural structure. Among various conversion methods, catalytic hydroconversion can depolymerize lignin and produce such aromatic compounds. In the present work, we illustrate the potential of this route by using sulfide catalysts in a batch reactor open for gas phase with a continuous feeding of H2, and equipped with a condensing reflux followed by cooled traps to remove continuously light products and water from the reacting mixture and recycle the H-donor solvent.
