| 摘要: |
| 将制得的具有相同比表面积和不同孔分布的超高比表面积活性炭用作吸附剂，研究活性炭吸附剂的孔分布对氢气吸附储存性能的影响。研究结果表明，氢气吸附储存性能明显受吸附剂孔分布的影响，活性炭吸附剂中孔(2nm0)；在吸附温度为273?K、压力为9.0?MPa时，中孔百分率为79.06?%的超高比表面积活性炭吸附剂上氢气脱附量达26.67?mmol·g-1。 |

| Abstract: |
| The influence of pore size distribution of super-high specific surface area activated carbon on hydrogen gas adsorption storage capacity was studied when the specific surface area is equal. The studies results indicated that the percent of mesoporous (2nm0).?At?273?K?and?9.0?MPa,?hydrogen?desorption?amount?reached?26.67?mmol·g-1 for the super-high specific surface area activated carbon with the percent of mesoporous reached 79.06 %. And the hydrogen desorption amount decrease with the increment of adsorption temperature. |
| Key words: Super-high specific surface area activated carbon adsorbent hydrogen adsorption storage pore size distribution |
