Abstract

A mathematical model of a continuous moving-bed temperature-swing adsorption (MBTSA) process for post-combustion CO 2 capture in a coal-fired power plant context has been developed. Process simulations have been done using single component isotherms and measured gas diffusion parameters of an activated carbon adsorbent. While a simple process configuration with no gas re-circulation gives quite low capture rate and CO 2 purity, 86% and 65%, respectively, more advanced process configurations where some of the captured gas is recirculated to the incoming flue gas drastically increase both the capture rate and CO 2 purity, the best configuration reaching capture rate of 86% and CO 2 purity of 98%. Further improvements can be achieved by using adsorbents with higher CO 2 /N 2 selectivity and/or higher temperature of the regeneration section.
