Summary
For this part of the project the studies focused on the development of novel sorbents for reducing the carbon dioxide emissions at high temperatures. Our studies focused on cesium doped CaO sorbents with respect to other major flue gas compounds in a wide temperature range. The thermo-gravimetric analysis of sorbents with loadings of CaO doped on 20 wt% cesium demonstrated high CO₂ sorption uptakes (up to 66 wt% CO₂/sorbent). It is remarkable to note that zero adsorption affinity for N₂, O₂, H₂O and NO at temperatures as high as 600 C was observed. For water vapor and nitrogen oxide we observed a positive effect for CO₂ adsorption. In the presence of steam, the CO₂ adsorption increased to the highest adsorption capacity of 77 wt% CO₂/sorbent. In the presence of nitrogen oxide, the final CO₂ uptake remained same, but the rate of adsorption was higher at the initial stages (10%) than the case where no nitrogen oxide was fed.
