“…These calculations were recently supported by Richter and Gobbels and Kaminaga et al who did not observed binary Ca–Y oxides for the samples calcinated at temperatures of 1500 and 1200 °C, respectively. On the other hand, Maeda et al assumed the formation of CaY 2 O 4 at the temperatures as low as 900 °C. Richter and Gobbels and Brown and Estell reported limited dissolution of the second component in the individual phases of CaO and Y 2 O 3 of about 1–2% at 1400 °C.…”

To improve the stability of high temperature CO 2 absorbent for sorption enhanced reforming applications yttria supported CaO were synthesized using two methods: calcination of mixed salt precursors and wet impregnation of yttria support. According to XRD data, CaO does not interact with the yttria matrix. However, introduction of CaO drastically changes the morphology of primary yttria particles. Increase in CaO concentration results in gradual plugging of the smaller pores and sintering of yttria support. The CO 2 absorption uptake in recarbonation-decomposition cycles increases with increase in CaO content and reach 9.6 wt % at CaO content of 19.9 wt %. CaO recarbonation extent varies from 49 to 77%. CaO/Y 2 O 3 absorbents are extremely stable under overheating and maintain their capacity in long series of decomposition-recarbonation cycles even after calcination at 1350 °C. The novel material resists moisture and retains its strength during storage in the air. According to tests, CaO/Y 2 O 3 can be considered as a promising CO 2 absorbent for fixed bed sorption enhanced hydrocarbons reforming.
