Abstract
Interest is increasing in re-examining mechanisms and kinetics for solvent extraction/hydrogenation of coal with the long-range goal of process optimization. This study deals with the rate of conversion of a bituminous coal to preasphaltenes, asphaltenes, and oils during dissolution in a donor solvent. Rate constants of the series/parallel reactions for formation of proasphaltenes, asphaltenes, and oils, and disappearance of unreacted coal are determined for the non-catalytic solvent extraction of coal in a hydrogen donor solvent (tetralin).
