Abstract

Abstract: The optimal reaction temperatures were investigated via the temperature programmed thermogravimetry， and the effects of particle size， species of binder， mixing ratio and reaction temperature on reduction reaction were studied via the isothermal thermogravimetry using STA409PC thermal analyzer. The results showed that the Cu-based oxygen carrier has the high reactivity of releasing oxygen when the temperatures are from 850℃ to 1000℃. The reaction rates have the tendency of increasing as particle sizes decrease and content ratios of binder increase， but the tendency is not apparent. The binders of SiO₂， ZrO₂ and TiO₂ combined with CuO show high reactivity and conversion ratio. The reaction rates increase greatly as the temperature increases.

Key words: chemical looping, air separation, oxygen production, Cu-based oxygen carrier, binder
