CO2 separation process using monolith adsorbent
A monolithic adsorbent has an advantage that the pressure drop in the bed is not severe even at high superficial gas velocity which is ideal for direct heating of the adsorbent for the TSA process. In designing the TSA process using monolith adsorbent, deciding the fraction of each zones, adsorption, desorption, and cooling zone, is the most important step. In this study, the adsorption and desorption dynamics of carbon dioxide on the monolith adsorbent is investigated as a first step toward optimum design and operation of the TSA process. The concentration of the CO2 used in this study was 12％ which is typical flue gas concentration of coal power plant. The breakthrough experiments revealed that sharper breakthrough curve is obtained at higher superficial velocity. Thermal regeneration of the adsorbent after saturation was conducted by circulating a part of the gas desorbed during the regeneration. The maximum CO2 concentration obtained by heating the adsorbent to 110 ℃ was 36％.
