A series of pyrolysis tests was carried out with samples with various ratio of lignite (brown coal) to sawdust biomass. Yields of individual pyrolysis products - liquid organic phase, pyrolysis water, pyrolysis solid products, and gaseous products were observed at the copyrolysis. Obtained organic liquid phase was hydrotreated in a hydrogenation reactor and the quality of all the samples was assessed then.
