摘要：

Rates of formation of oil, asphaltenes, and preasphaltenes during solvent extraction of a high-volatile A bituminous coal have been experimentally determined. A mathematical model that adequately describes the observed data has been developed, and pseudo-first-order rate constants for each of the indicated mechanistic steps have been calculated by nonlinear regression. The results of the study show rapid conversion of the reactive maceral fraction of the coal to liquid products and indicate that stable intermediates which are resistant to further hydrogenation at solvent-refining conditions are present in the reactor at long reaction times. © 1979, American Chemical Society.
