Abstract:	A close relation has been found between hydrogen evolution from coal-catalyst and pitch-catalyst systems and catalytic activities of liquefaction reactions. A MoO₃?TiO₂ catalyst has the highest activity and the order of activity of the catalysts for hydrogen evolution is: MoO₃?TiO₃> MoO₃?SiO₂>10% $Fe_{2} O_{3} TiO_{2} ?AI_{2} O_{3} > coal alone$ . The same trend was observed for benzene-soluble materials for the hydrocracking of Akabira Coal.

Keywords:	coal coal liquefaction catalysis dehydrogenation
