摘要：
Mathematical models are proposed to describe the extraction kinetics within a bed of coal particles by organic solvents in a wide range of temperature, pressure, flow rate of the solvent and coal particle size. Calculations show, that molecular diffusion determines the extraction process at average particle diameters DBAR(K) > 0,8 mm.
