Abstract: | Abstract In this study, a new preparation method providing greatly improved CO2 sorption is introduced. Li2ZrO3 sorbent was prepared by low temperature co‐precipitation and compared in CO2 sorption performance with a sorbent prepared by the conventional high temperature solid‐state reaction method. The two sorbents were characterized using scanning electron microscopy, X‐ray diffraction and thermo‐gravimetric analysis. The Li2ZrO3 powder prepared by the relatively simple co‐precipitation method showed significantly better performance than the one prepared by solid‐state reaction with respect to both kinetics and CO2 sorption capacity. Extensive study of the powder prepared by co‐precipitation has been performed at various conditions. |
