“…The dehumidifier was applied later to the adsorptive desiccant cooling system, and the heat/mass transfer properties of the dehumidifier itself and the cooling system have been analyzed by Kodama et al, − Okano et al, and Jin et al Recently, Matsukuma et al , analyzed a potential application of the honeycomb rotor adsorber to CO 2 recovery other than dehumidification. As for the thermal swing VOC concentrator, thermal effects for a cyclic adsorption process have been discussed by Ko et al, Gales et al, Sullivan et al, Nastaj et al., and Matsukuma et al , However, they discussed particle packed beds 8-11 instead of honeycomb type, a combined temperature-pressure swing 11 or numerical simulation, but not experimental works. − No papers based on experimental data seem available except for a conference paper by Kuma et al and a short paper by Mitsuma et al within the authors' scope. Keller timely outlined the honeycomb rotor adsorber in his review of adsorption technology, but only a few engineering data are published yet, as he said.…”

Fine powder of hydrophobic high silica zeolite was solidified with silica sol in the void of a 0.2 mm thick ceramic fiber sheet fabricated into a honeycomb structure, typically with 3.2 mm pitch × 1.7 mm height. The honeycomb rotor of adsorbent was applied to the VOC abatement system operating with thermal swing adsorption. Dependence of the removal efficiency of VOC on various variables was investigated for a test honeycomb rotor of 300 mm in diameter. The following operating guide was recommended to reach high performance where more than 95% of VOC in the feed gas is removed: superficial velocity of feed air = 2−4 m/s, flow rate ratio of process to regeneration zone = 5−15, relative humidity < 80%, and regeneration air temperature = 180 °C with rotation speed optimized. The optimal rotation speed of the honeycomb rotor was investigated closely, and the result was interpreted in terms of the heat capacity ratio between the honeycomb rotor and the regeneration air stream.
