摘要: To improve the stability of high temperature CO2 absorbent for sorption enhanced reforming applications yttria supported CaO were synthesized using two methods: calcination mixed salt precursors and wet impregnation support. According to XRD data, does not interact with matrix. However, introduction drastically changes morphology primary particles. Increase in concentration results gradual plugging smaller pores sintering The absorption uptake recarbonation-decomposition cycles increases increase content reach 9.6 wt % at 19.9 %. recarbonation extent varies from 49 77%. CaO/Y2O3 absorbents are extremely stable under overheating maintain their capacity long series decomposition-recarbonation even after 1350 °C. novel material resists moisture retains its strength during storage air. tests, can be considered...
