| Research Abstract |
Separation performance of thermal swing adsorption TSA process equipped with steam regeneration step was investigated for removal of CO2 exhaustedfrom thermal power plants and so on. It was found that the steam regeneration could produce relatively high CO2 concentration in enriched gas. Also separation of a simulated biogas consisting of CO2, CH4 and water vapor by pressure swing adsorption PSA process was experimentally tested for the enrichment of CH4. PSA process employed SAPO-34, which was originally developed as an adsorbent for water vapor, kept its separation performance for the feed gas containing a small amount of water vapor.
