Abstract
The honeycomb adsorbent was prepared for adsorbing and separating carbon dioxide from combustion exhaust gas, which had deep impact on climate change, and the characteristics of the adsorbent were studied. Na-X zeolite was coated on a honeycomb prepared with ceramic sheet or active carbon sheet so that the two honycomb can be used at high temperature. Third honeycomb adsorbent was prepared by using zeolite sheet, which contained zeolite as component. The steady-state adsorption properties and surface morphologies were analyzed and breakthrough characteristics were ananlyzed by providing 16% carbon dioxide mixed gas. By thermal regeneration, carbon dioxide concentration properties were analyzed, and the adsorptive separation process was compared between thermal swing adsorption and pressure swing adsorption after adsorbent temperature change during heating. The breakthrough results of the honeycomb showed possibility of rotary adsorptive concentration process.
