CaO-based sorbent

ultrasonic spray py performance. All materials were characterized by XRD, STEM, TEM, combustion (e.g., silica supported amines,2 zeolites,3 activated carbons4) and for “pre-combustion”, i.e., aer water–gas shi (WGS) but before power generation (e.g., CaO,5 lithium zirco-nates,6 hydrotalcites,7 and metal–organic frameworks8). Sorbents that operate at relatively high temperature (i.e. CaO) are particularly attractive choices integrate with WGS or methane sorbent microstructure to improve the sorbent stability.16 Additionally, it has been shown that the sorbent can be partially regenerated upon hydration.17 Aerosol synthesis methods have been extensively utilized to prepare a variety of metal oxides, even on an industrial scale.18,1
