Outline of Final Research Achievements

Removal of impurities in biogas, such as carbon dioxide CO2, hydrogen sulfide H2S and siloxane, is absolutely imperative for effective utilization of methane generated by anaerobic fermentation of sewage sludge. This research aimed at development of target-molecule-capture type adsorbents composite and its application to gas separation-concentration system. As a result, a sodium type of a low silica zeolite is the most suitable as an adsorbent of CO2. An active carbon with highly-dispersed transition metal oxide is effective as an adsorbent of H2S. An activated carbon adsorbent with controlled surface polarity and pore sizes has promise as a siloxane adsorbent. A target-molecule-capture type adsorbents composite is developed by combination of these adsorbents.
