CO2 Capture Test for A Moving-bed System Utilizi g Low-temperature Steam

Abstract

In the process of capturing CO2 from flue gas (combustion exhaust gas), the lowering of CO2 capture energy is considered a significant issue. If some or all of the CO2 capture energy can be compensated with the waste heat, a significant energy saving is possible. In our proposed CO2 adsorption process, because the CO2 is captured using low-temperature steam, an energy-s ving process that makes it is easy to utilize the waste heat can be created. In this paper, we conduct bench tests aimed at developing a mo ing-bed system suitable for large-scale plants in order to verify the performance of the adsorbent. The results demonstrated that an moving-bed system could be established to capture 1.6t/day of CO2 from coal combustion exhaust gas.
