Abstract In this paper synthesized palladium (Pd)-containing catalysts were used in the hydrogenolysis of lignin presence a hydrogen donor solvent, i-propanol, to obtain liquid fuel components. A study influence catalyst support nature, preparation method and supercritical solvent nature on depolymerization was completed. It found that use Pd-containing results formation aromatic compounds (mainly benzene toluene) for both solvents (i-propanol CO 2 ). The maximum conversion (50 %) achieved when i-propanol selectivity aromatics (over 70 observed by hydrothermal deposition polymeric matrix hyper-crosslinked polystyrene.
