摘要/Abstract

摘要： 利用STA409PC综合热分析仪以升温速率热重法研究了铜基氧载体最佳释氧温度；以等温热重法研究了氧载体的颗粒直径、惰性载体种类、混合比率及反应温度对释氧性能的影响.实验结果表明:铜基氧载体的最佳释氧温度为850~1000℃.随氧载体粒径的减小和惰性载体比率的增加氧载体释氧速率在逐渐增大但变化不大；二氧化硅、二氧化锆和二氧化钛为惰性载体制备的铜基氧载体表现了高的释氧速率和转化率；反应温度对释氧性能影响很大，随反应温度的增加，氧载体的释氧速率明显增大.

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
