HYDRATION AND PELLETIZATION OF CaCO3-DERIVED SORBENTS FOR IN-SITU CO2 CAPTURE

摘要：

Steam hydration and pelletization of limestone were investigated using a thermogravimetric analyzer (TGA) to improve the sorbent utilization for in-situ CO2 capture under typical fluidized bed combustion (FBC) operating conditions. Steam hydration of CaO improves carbonation capacity but the hydrated sorbent is very fragile, which will be a problem for FBC applications. Similar sorbent improvements in terms of maintaining/enhancing reactivity were observed by sorbent fine grinding and pelletization, which appears to be a method of using hydrated sorbent in fluidized bed applications.
