Dissolution kinetics of the mix of thermobitumen and oil (TBO) formed at low-temperature pyrolysis of oil shale in autoclaves was studied for the first time. The pyrolysis temperature was varied in the range of 350-370℃ and duration between 3 and 9 hours. The dissolution of TBO obtained was conducted in a thermostated stirred class reactor and evaluated by the increase in optical density of the solutions with time varying temperature (25-60℃) and solvent type (benzene, toluene, oil shale petrol and ethanol). A mathematical model was deduced for quantitative description of dissolution kinetics by approximation of the process to the first-order parallel dissolution of two fractions. The dissolution rate coefficients for the fractions were estimated, and contribution of their partial optical densities on the current optical density was described under the conditions studied.
