| 摘 要： | 采用常压吸附法研究了膨胀石墨吸附剂在二氧化碳/氮气体系中对二氧化碳的动态吸附性能,比较了其吸附量、穿透曲线和吸附性能的差异.研究了膨胀石墨的比表面积,孔径分布等因素对其二氧化碳吸附性能的影响.结果表明:膨胀体积越大的膨胀石墨,其对二氧化碳的吸附能力越强,最高可达190 mg/g以上.其吸附量随温度升高而呈现下降趋势,但在30℃时吸附量仍达到90 mg/g以上.

| Abstract: | A study of dynamic adsorption of characteristics of carbon dioxide in CO2/N2 gas mixtures on expanded graphite at atmospheric pressure is reported.Correlations of breakthrough curves,and carbon dioxide saturated adsorption quantities with the physical properties are studied.It is found that the larger expanded volume of the expanded graphite has the more carbon dioxide which expanded graphite can adsorb.The properties adsorption can reach over 190mg/g.It has reduced to over 90 mg/g as the temperatures is ra... |
