| 摘要: |
CO2 capture was carried out over dry K2CO3/MgO/Al2O3 sorbent in a fluidized-bed reactor. The result showed that the total CO2 adsorption capacity of the new sorbent reached 109.6 mg of CO2/g of sorbent in the bubbling regime at 60 C. The X-ray diffraction (XRD) results revealed that there were several kinds of carbonates formed duringCO2 adsorption, such asKHCO3, KAl(CO3)2(OH)2, K2Mg(CO3)2, K2Mg(CO3)2 3 4H2O, and MgCO3. The high concentrationCO2 could be obtained by themultistage adsorption/desorption cycles. The sorbent could be completely regenerated at 480 C, and the adsorption capacity remained
unchanged after 6 cycles. Furthermore, the application of a conceptual CO2-capture process using this sorbent was proposed for an existing coal-fired power plant. |
