Development of CaO-based Mixed Oxides as Stable Sorbents for Post-Combustion CO2 Capture Via Carbonate Looping

A promising concept for post-combustion CO2 capture is carbonate looping, in which CO2 is captured at high temperature using calcium-based sorbents. The process suffers from degradation of the materials and decrease of CO2 capacity after multiple calcination/carbonation cycles. In this paper, we report the development of stable synthetic and natural mixed CaO-based sorbents for post-combustion CO2 capture from industrial plans flues gases. The promoted synthetic sorbents, synthesized via a sol-gel auto-combustion method, exhibited very stable performance for 100 consecutive sorption/desorption cycles and an increased CO2 uptake capacity. Promising performance was also achieved with a natural sorbents consisting of industrial water- treated hydrated lime mixed with a kaolin and/or MgO binder.
