Abstract

Experiments were performed for heat and mass transfer in thin packed beds of silica gel A and zeolite 13 X adsorbing steam. The adsorption rate decreased in both the silica gel and zeolite beds . as the bed thickness increased, while the reduction of the adsorption rate with decreasing the adsorbent grain size was found only in the zeolite bed. It was confirmed that these reductions were attributed partly to a non-negligible resistance to mass transfer in the interstices of grains, in addition to a resistance to heat conduction within the bed. There was an optimum bed thickness at which the amount of adsorbed water per heat transfer surface area became maximum, because it depended on the adsorption rate and the amount of packed adsorbent. In a consolidated bed, an improvement of adsorption rate was observed in the latter half of reaction time. The adsorption rates at various conditions could be expressed by a single non-dimensional equation.
