SINOPSIS: -The solubilization of coals by solvolysis reactions was investigated using petroleum asphalt pitch prepared by heat-treated Khafji vacuum residue.<BR>It was found that the degree of solubilization was dependent on the rank of coal as well as reaction tempreture. Microscopic observations on the solvolysis pitches from Miike coal-asphalt pitch showed dissolution of coal particles into solvent (asphalt pitch). Among the coals examined, Miike coal (C: 82. 9%) was most efficiently solubilized into the asphalt pitch prepared at 420°C for 1 hr, when the solvolysis reactions were carried out in the tempreture range from 380 to 390°C.
