A Plexiglas reactor was constructed and experiments carried out with three mixer configurations in a sand-water system to determine the best mixer configuration and the minimum rpm to produce uniform conditions during coal dissolution. Coal dissolution experiments on Kentucky No. 9 coal were made with combinations of tetralin and 2-methylnaphthalene to obtain the optimum ratio in the solvent. The effect of ..beta..-naphthol addition to the solvent on the dissolution of Kentucky No. 9 coal was studied. The effect of holding time at 400/sup 0/C on the dissolution of Kentucky No. 9 coal in a solvent containing 46.1 wt % tetralin, 46.1 wt % 2-methylnaphthalene, 2.9 wt % ..gamma..-picoline and 4.9 wt % ..beta..-naphthol was studied.
