For development of highly active iron catalyst on coal hydroliquefaction, correlation between the activity on the hydrogenation of aromatic hydrocarbons with metallic iron (Fe) and iron sulfides prepared in the various S/Fe ratios and the amount and the strength of adsorbed hydrogen to the surface with TPD method were studied. Aromatic hydrocarbons were strongly adsorbed and hydrogen molecule was weakly adsorbed the moderate amount to the Fe surface. On the other hand, pyrrhotite (Fe_<1-x>S) adsorbed a lot of hydrogen strongly, but did not adsorbed the aromatic hydrocarbons strongly. However, troilite (FeS) and the mixture of Fe and FeS adsorbed a little of hydrogen strongly.
