摘要：

Multi-cyclic CaO carbonation/calcination is an attractive method for CO2 capture during coal combustion. However, the capture capacity of CaO sharply decreases with increasing carbonation/calcination cycles. In order to improve the stability of CO, capture capacity of CaO during carbonation/calcination cycles, synthetic CaO/Al2O3 sorbents were synthesized by two methods: wet chemistry and sol gel-combustion-synthesis (SGCS) to make a further comparison. The results indicate that the SGCS-made CaO/Al2O3 = 80:20 wt% sorbent provides a competitive performance of a capture capacity of 0.43 g-CO2/g-sorbent after 20 cycles. (C) 2010 Ying Zheng.
