| Popis: | 5 Figures, 4 Tables.-- Work presented at the 13th International Conference on Greenhouse Gas Control Technologies, GHGT-13, 14-18 November 2016, Lausanne, Switzerland. New cost effective and high performance bi-functional composite materials consisting of CaO and CuO supported on Ca12Al14O33 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% Ca12Al14O33 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. The presented work is funded within the ASCENT project as part of the European Union’s Seventh Framework Program (FP7/2007-2013) under grant agreement nº 608512. |
