Abstract

Abstract: New cost effective and high performance bi-functional composite materials consisting of CaO and CuO supported on Ca12 Al14 O33 have been developed for the calcium-copper (Ca-Cu) looping process. A hydrothermal method has been used to synthesize the materials from low cost precursors. Prepared composites are characterised by X-ray diffraction, scanning electron microscopy together with energy-dispersive spectroscopy mapping, and by crushing strength tests. Long term chemical performances of the materials are tested in a thermo-gravimetric analyser. The composite containing 53 wt% CuO, 22 wt% CaO and 25 wt% Ca12 Al14 O33 shows stable CO2 capture (∼15 g-CO2 /100 g composite) and O2 carrying capacity (∼7 g-O2 /100 g composite) in long term Ca-Cu multi-cycle, and shows satisfactory mechanical strength compared to reference materials used in the Ca-Cu process.
