Pressure drops and gas flow in parallel-packed beds with two kinds of particles have been theoretically and experimentally studied. Gas flow behaviors in this sort of the bed can not be interpreted by means of simple theories only for the axial velocity of gas. Even with the axial insulation with a partitioning glass tube, the parallel-packed bed yields the lateral cross-flow within a thicker distributer. Also, the cross flow generally exists in the parallel-packed bed, so far as the flow resistance of the distributer is finite. In both cases the pressure drop lies between the values calculated theoretically on the parallel and series models of gas flow. Taking account of the existence of the cross-flow in the bed, a lumped parameter-model is proposed and the experimentally observed behaviors of the pressure drop are reasonably explained.
