抄録

The hydrogenolysis reactions of demineralized Adaro subbituminous coal exchanged with several kinds of cations were carried out. The upgrading reaction occurred significantly on the hydrogenolysis of Fe^<2+>, Ni^<2+> or Co^<2+> exchanged coal. Further, the reactions of these cation exchanged coals were enhanced by sulfur addition. However, the addition of Fe_2O_3 with sulfur, Ni_3S_2 or CoS did not enhance the reaction of demineralized Adaro coal. Therefore, the upgrading on the hydrogenolyses of these cation exchanged coals were caused by the highly dispersed cations into the coal matrix through the ion exchange with carboxylic groups in the coal molecules.
