To evaluate the hydrogen adsorption performance of the typical carbon based adsorbents from the aspect of adsorption heat, nonlocal density functional theory(NDFT),Carnahan-Starling, MBWR equations of state and the mean-field theory are used to determine the bulk density and density profiles of hydrogen molecules within the adsorption space.The adsorption density is obtained from the weighted average of the density profile calculated with NDFT in the width (or radial) direction of adsorption space. The maximum physical adsorption capacities of hydrogen molecules in the close-packing state are used to calculate the isosteric heat of adsorption. The adsorption isotherms at 77-297 K with a step of 10 K and 1-10 MPa with a step of 1 kPa are first determined,then,the isosteric heat of adsorption on three typical carbon based adsorbents are ascertained by the adsorbed phase volume and the bulk gas volume in thermodynamic equilibrium during the adsorption process.From the comparisons among the results from the NDFT calculation and experimental data,not only the isotherms of hydrogen adsorption on carbon nanotubes have similar figure to those of activated carbon,but also the values of isosteric heat of adsorption on these adsorbents are within the same range.Finally,the measure that the accurate hydrogen adsorption experiments on pure carbon nanotubes should be carried out to verify their physical adsorption performance,and the effective measures for the management of adsorption heat should also be emphasized while considering the cryogenic adsorption of hydrogen in carbon nanotubes.

为比较狭缝孔、纳米管两种典型碳基吸附剂的储氢性能 ,应用非局域密度泛函理论、微观物理学、吸附平衡原理、典型吸附剂储氢试验结果计算并分析了典型碳基吸附剂的氢等量吸附热 .结果表明 ,两类吸附剂的氢等量吸附热相差不大 ,等温线变化规律相似 ,并且只有在低温 (液氮 )、适度压力时吸附储氢的质量密度才有望达到DOE标准 .

Cryogenic adsorption of hydrogen isotopes on porous adsorbents is an attractive method for tritium re-covery from helium which conducts as sweep gas of tritium breeding blanket in a fusion reactor. In order to use this method to extract tritium effectively, it is necessary to investigate adsorption properties of various candidate adsorb-ents. In this study isotherms and isotopic effects of hydrogen isotopes on three carbonaceous adsorbents: carbon mo-lecular sieve, activated carbon and carbon nano-fiber have been tested at liquid nitrogen temperature. It was con-cluded that the first two adsorbents could be used for this purpose and the third one was excluded because of its low adsorption capacity. Adsorbent modification using concentrated HNO3 and experimental results of the modified ad-sorbents have also been reported.

采用穿透曲线法研究了液氮温度下活性炭、碳分子筛和碳纳米纤维对氢同位素的吸附等温线和同位素效应。结果表明:活性炭和碳分子筛都是良好的吸附剂,碳纳米纤维对氢同位素的吸附量太低而不具备工程应用的可能性。实验还对吸附剂进行了改性处理,考察了改性吸附剂对氢同位素的吸附性能。
