Catalytic hydrogenation using Co/Mo catalyst was carried out to selectively cleave methylene bridges in coal. Hexane and benzene soluble compounds were characterized by g.c.-m.s. The structural changes in original coal and hydrogenated coal were studied by C-13 CP/MAS n.m.r. supplemented by variable contact time, dipolar dephasing, inversion recovery and spin echo techniques. A good treatment has been found between the g.c.-m.s. and C-13 CP/MAS n.m.r. analyses.
