Catalytic hydrogenolysis of different types of lignin obtained from the softwood sawdust

The article contains results of the process of hydrogenolysis of lignin obtained by three different methods from softwood sawdust. It is shown that the extraction process has a profound effect on the feedstock conversion and the product yield. The maximum conversion of 67.5 was observed in the case of acetate lignin in propanol-2 as the solvent, and the highest yield of liquid products (38.5 wt. %) was obtained in the case of alkali lignin.
