摘要：
Montan wax extraction which is considered to be an application of solid-liquid extraction (leaching) was systematically studied. Different mass transfer models for Montan wax extraction of brown coal-toluene system are established to simulate and analyse the extraction process with fixed-bed extractors and stirred extractors. Empirical correlations are applied to determine the mass transfer coefficients is proposed for the Montan wax extraction, which is validated by using sets of experimental data in percolation columns and stirred extractors.
