Dataset description

Calcium oxide-based sorbents were coated onto Saffil ceramic fibres by means of a wet impregnation method. The effect of synthesis parameters on the crystalline structure, morphology and texture of the CaO layer were investigated by X-ray diffraction, scanning electron microscopy and gas adsorption techniques. The analyses revealed that the optimised synthesis method produced a uniform coating composed of a network of CaO nanoflakes. The evaluation of the materials as CO2 sorbents was performed under repeated carbonation-decarbonation cycles using thermogravimetric analysis (TGA). A nominal 25 wt. % loading of CaO gave a CO2 uptake capacity of 0.118 mg CO2/mg of sorbent (carbonation at 650°C in 90% CO2 and decarbonation at 850°C in N2). A 5 wt. % loading exhibited improved durability with a ~30% decay in carrying capacity after 30 TGA cycles, but at the expense of initial uptake capacity.
