Liquefaction of a high volatile A coal and vitrinite, liptinite, and inertinite concentrates was performed at 385, 427, and 445°C for 15 min residence time, using tetralin solvent in a hydrogen atmosphere. Examination of the solid liquefactiob residues indicated that each maceral group was more resistant to conversion in concentration than in combination.
