Adsorptive permeation hollow fiber membrane (APM) has been developed for effectively separating CO₂ fromgas mixture. Inside the APM, zeolite 13X particles were uniformly dispersed without covering their surfaces by a symmetricporous structure of polypropylene lattice. In this study, CO₂/N₂ mixture was used as a simulated gas mixture. Separation wasachieved by adsorbing CO₂ on the zeolite particles in the APM and then permeating N₂ into permeate side in passing all thefeed gas through the APM. Adsorptive permeation tests were carried out with a set of APM modules, and the adsorptivepermeation performances of the modules were analyzed from the test results. After saturation of the adsorbent with CO₂, theAPM was regenerated by desorption of CO₂ from it through vacuuming both inside of outside of the APM hollow fiber,and the regeneration process of the APM by vacuuming was discussed in terms of regeneration efficiency and energyconsumption.
