摘要：

In this work, a series of Zr and Li incorporated synthetic CaO based sorbents were prepared by a simple precipitation method for high temperature (600-800 degrees C) CO2 capture. After impregnation and subsequent calcination, the sorbents were characterized by N-2 adsorption isotherm, scanning electron microscopy and X-ray diffraction techniques. The cyclic performance in CO2 processes was evaluated by breakthrough measurements. ZrCa3Li4O7 exhibited the maximum CO2 sorption of 28.4 wt% and it showed excellent stability. The CO2 performance of ZrCa3Li4O7 still remained stable when tested under a high decarbonation temperature of 900 degrees C.
