Catalytic hydrogenation of coal was investigated for Morwell-B (Aus-tralian), Taiheiyo (Japanese) and Sumiyoshi coal, the following results being obtained: under experimental conditions where char was not formed, (1) Morwell-B and Sumiyoshi coal were decomposed by the paralel scheme in which a less reactive component, coal<SUB>1</SUB>, and the reminder, coal<SUB>2</SUB>, in coal were consumed each through their respective paths.Taiheiyo coal was decomposed, on the whole, by a single scheme; (2) according to macrokinetical analysis, a decomposition rate of coal<SUB>1</SUB>was half order with respect to hydrogen partial pre-ssure and showed an exponential increase with increasing catalyst concentration, that of coal<SUB>2</SUB> being first order with respect to hydrogen partial pressure and approximatly independent on catalyst concentration; (3) the kinetical information indicates that coali and coal<SUB>2</SUB> decompose catalyticaly through a reaction involving dissociated hydrogene and non-catalyticaly through a reaction involving molecular hydrogen, respectively.
