A continuous pump in which the feed and product streams flow steadily both in upflow and downflow is experimentally investigated in the model system toluene‐n‐heptane on silica gel adsorbent. The experimental data compare reasonably well with analytical results based on an equilibrium theory. The operating conditions necessary to achieve high separation factors are shown to be dependent on the relative magnitudes of penetration distances and the height of the column.
