Ceramic paper sheets were formed into a honeycomb rotor with inorganic adhesive and it was calcined at about 500°C. The honeycomb adsorbent was impregnated with high-silica zeolite powder by a chemical reaction being dipped into a solution that contains zeolite powder and silica sol as an inorganic binder of the zeolite powder. After dried and finished, it was set in a SUS tube with insulation spacer and installed in testing equipment.VOC vapor, butylacetate, was generated and directed to the honeycomb adsorbent, laden in the feed air stream, to conduct the adsorption and desorption efficiency test of the honeycomb adsorbent for this VOC. The test was done in a cyclic manner by feeding the air stream to the honeycomb adsorbent (adsorption process), and reversing the direction of the stream which was heated up (desorption process), with sequential damper arrangement and with scheduled periodic time control.The result was compared with the one obtained by the conventional rotary test runs of the honeycomb adsorbent and was evaluated for a new trial of efficiency prediction method.
