Abstract
- Calcium looping is one of the effective methods for post‐combustion CO2 capture. A key issue is choosing the appropriate supports to synthesize effective calcium‐based sorbents. In this study, calcium looping sorbents incorporated with MgO, Ca3Al2O6, and MgAl2O4 supports were prepared by wet‐mixing synthesis. Characterizations were made to determine the cyclic CO2 capture capacity, crystalline structure, porosity, and morphological changes of the sorbents over multiple cycles. The results showed that, at the mass ratio of CaO to support oxides of 7:3, the MgAl2O4 mixed support showed better CO2 capture performance than the MgO and Ca3Al2O6 supports. Moreover, the sorbent showed a porous and fluffy microstructure with a high specific surface area, making it a suitable candidate for cyclic CO2 capture. [ABSTRACT FROM AUTHOR]
