“…Several papers have dealt with the performance evaluation of oxy-coal combustion power generation systems including overall reviews and specific issues (Okawa et al, 1997;Andersson and Johnsson, 2006;Seltzer et al, 2006;Kakaras et al, 2007;Rezvani et al, 2007;Bouillon et al, 2009). The results of these studies have shown that a drop of the net efficiency, of more than 8% is expected to occur, and that system integration is required to lower the penalty caused by CO 2 capture.…”

“…Effect of O 2 on CO 2 Adsorption of MIP. Figure 6 reports six CO 2 breakthrough curves obtained at different O 2 flow rates, namely 0, 8,9,10,11, and 12 mL/min, respectively. Only slight changes were observed on these curves with the variation of O 2 concentration, which can be attributed to experimental error.…”

CO2 separation by molecularly imprinted adsorbent from coal-fired flue gas after desulfurization system has been studied. The adsorbent was synthesized by molecular imprinted technique, using ethanedioic acid, acrylamide, and ethylene glycol dimethacrylate as the template, functional monomer, and cross-linker, respectively. According to the conditions of coal-fired flue gas, the influencing factors, including adsorption temperature, desorption temperature, gas flow rate, and concentrations of CO2, H2O, O2, SO2, and NO, were studied by fixed bed breakthrough experiments. The experimental conditions were optimized to gain the best adsorption performance and reduce unnecessary energy consumption in future practical use. The optimized adsorption temperature, desorption temperature, concentrations of CO2, and gas flow rate are 60 °C, 80 °C, 13%, and 170 mL/min, respectively, which correspond to conditions of practical flue gases to the most extent. The CO2 adsorption performance was nearly unaffected by H2O, O2, and NO in the flue gas, and was promoted by SO2 within the emission limit stipulated in the Chinese emission standards of air pollutants for a thermal power plant. The maximum CO2 adsorption capacity, 0.57 mmol/g, was obtained under the optimized experimental conditions, and the SO2 concentration was 150 mg/m(3). The influence mechanisms of H2O, O2, SO2, and NO on CO2 adsorption capacity were investigated by infrared spectroscopic analysis.

“…Several different CO 2 capture processes are currently being developed, such as IGCC process, oxyfuel combustion, or amine scrubbing. However, these processes have the disadvantage of enormous energetic efficiency losses of 8-14% points leading to a significant increase in fuel consumption (Strömberg, 2001;Bouillon et al, 2009;Ekström et al, 2009;Martelli et al, 2009). Chemical looping combustion (Anheden and Svedberg, 1998;Abad et al, 2007;Leion et al, 2008) allows the separation of CO 2 with a very low energy penalty, but still requires substantial research and development until full-scale realization, particularly for coal conversion.…”
