摘要 研究了液氮温度下活性炭(AC)、碳分子筛(601)和碳纳米纤维(CNF)对H2、D2的吸附等温线,采用2种Langmuir模型对它们吸附H2、D2的等温线进行了理论计算。研究结果表明:在液氮温度下,3种碳基吸附剂对氢同位素的吸附等温线遵从Langmuir单分子层吸附模型,符合按活性点分类的定点吸附机制;吸附等温线可用Langmuir多项式理论模型进行准确计算。 Adsorption isotherms of H2 and D2 on activated carbon(AC), carbon molecular sieve(601) and carbon nanofibers(CNF) are investigated at the liquid nitrogen temperature. Both the onesite and twosite Langmuir models are used for isotherm calculation. Results indicate that all isotherms of H2 and D2 on AC, 601 and CNF can be expressed well with the twosite Langmuir model. Accordingly, it can be inferred that, while adsorbed on carbonaceous adsorbents at the liquid nitrogen temperature, hydrogen isotope molecules should occupy the multiple types of active sites to form a localized monolayer.
