Abstract

Recent attempts to improve the attrition resistance and CO2 uptake of Ca-based sorbent by making pellets with aluminate cement have succeeded in enhancing their effectiveness. The effects of parameters on sorbent attrition were investigated. Batch experiments were also conducted in a fluidized bed at optimal reaction conditions from previous studies (Carbonation: 0.5MPa and 700°C in 15% CO2/air balance for 15min; Calcination: 0.1MPa and 950°C in 100% CO2 for 10min). The pore structure characteristics (BET,BJH) were measured as a supplement to the attrition and reaction studies. Results showed that the mechanical property of the pellets with the particle size of 1.0–1.43mm were greatly enhanced, especially for the pellet CaO–0.5% CLS-A. A slow decay in CO2 capture capacity of the sorbents was observed after making pellets during multiple cycles. It was attributed to the attrition of sorbents and the exposure of inner core of the CaO sorbents, which are in favor of CO2 capture. The pore structure showed that the BET surface area and BJH pore volume did not change much, which benefits CO2 uptake of the sorbents during the cycling.
