| 摘 要： | 实验测定了炭分子筛的ＣＯ２比表面积和Ｎ２比表面积。结果表明，炭分子筛ＣＯ２比表面积和Ｎ２比表面积的差值（ＳＣＯ２－ＳＮ２）可反映炭分子筛有效微孔的数量，比值（ＳＣＯ２－ＳＮ２）／ＳＣＯ２可定性表征炭分子筛有效微孔的相对含量和空分性能，比值（ＳＣＯ２－ＳＮ２）／ＳＣＯ２（记为Ｘ）和炭分子筛空分性能Ｎ２％（记为Ｙ）之间存在近似定量关系Ｙ＝９７．０３－１１．９９Ｘ＋１５．１２Ｘ２。

| Abstract: | The CO2 and N2 specific surface areas of the carbon molecular sieves (CMS) produced from walnut shells under different conditions are measured. The result shows that the (SCO2-SN2)/SCO2 value represents the ratio of those micropores effective to air separation to the total micropores. There is a statistical relationship between the (SCO2-SN2)/SCO2 (marked as X) and the air separation ability N2% (marked as Y) of the CMS formulated as follows: Y=97.03-11.99X 15.12X2 . |
