Lignin properties were improved by electrochemical :hydrogenation. Various technological factors, such as cathode materials, temperature and concentrations of water, solvent, substrate, on the electrochemical hydrogenation of lignin in divided electrolytic cell were,studied. The results showed that the hydrogen, content (H %) and ratio of hydrogen to carbon (H/C) of hydrogenated lignin (HL) increased by 1.7 % and 0.04, respectively, and the softening point (SR) decreased by 24degreesC in comparison with lignin raw material. It was feasible for lignin to be electrochemically hydrogenated.
