The calcium looping is a promising technology to achieve industrial CO2 capture, and the introduction of oxygen vacancy can promote capture reactivity CaO-based sorbents. In this work, DFT calculations were performed investigate adsorption by CaO in presence defect. reduces band gap surface, which results from delocalization Ca 2p orbital. Besides, electron accumulation at occurs due unsaturated Ca-O bonds, reaction possibility promoted neighbouring top site defect favourable for adsorption....
Calcium looping is one of the most promising technologies for large-scale CO2 capture, while CaO-based materials suffer from deactivation in capture capacity multiple carbonation/calcination cycles as a result sintering. Ce-promoted CaO considered an effective sorbent during calcium cycles. In this paper, adsorption performance presence steam was investigated using density functional theory (DFT) calculations. The cyclic tested to confirm feasibility DFT Moreover, structural and parameters,...
A synthetic sorbent prepared from carbide slag and dolomite by combustion exhibits high CO<sub>2</sub> capture capacity, good cyclic stability a porous microstructure.
Abstract CaO/Ca(OH) 2 thermochemical heat storage (THS) technology is considered to be one of the most promising technologies for large‐scale solar energy storage. However, THS performance raw CaO‐based materials decreases during multiple cycles. In this work, CaO derived from calcium acetate (Ac‐CaO) prepared and applied a coupled system that achieved simultaneous CO capture. The capture performances Ac‐CaO are always higher than those calcined limestone owing preferable pore structure,...
