The behaviour of Kolubara soft brown coal during direct liquefaction by catalytic hydrogenation was studied and was compared with the Banovići brown coal investigated previously. A sample of washed and dried coal was ground dry, or was ground in the presence of different liquids. Addition of water during grinding resulted in a somewhat coarser granular composition, while n-heptane did not have a noticeable effect. High reactivity of the soft brown coal, which initially was indicated by thermal analysis, was confirmed by high yields of liquid products, particularly of oils soluble in n-heptane. The solid liquefaction residues did not contain pyrolytic carbon and cenospheres, and contained a low proportion of humoplasts indicating the high liquefaction efficiency of the coal in spite of its high content of xylite.
