摘　　要：由高硫焦制备出一系列超级活性炭 ,并在 0～ 10MPa、93～ 2 93K范围内 ,考察了SBET 为 3886m2 ·g- 1的超级活性炭对氢的吸附、解吸特性。结果表明 ,氢的吸附能力随超级活性炭比表面积的升高而增加 ,随着温度的降低而增大 ;在 2 93K 5MPa、93K 6MPa条件下 ,储氢质量分数分别达 1 9wt%、9 8wt% ;氢的等温脱附率为95 9%A series of super activated carbons were prepared by high sulfur pertroleum cokes.The properties of super activated carbon for H 2 storage were studied systemically in the range of 93～293K at 20K intervas and pressure up to 10MPa.The results showed that hydrogen storage capacities increased with the surface area of super activated carbon.The amounts of adsorbed hydrogen by weight were respectively 1 9wt%、9 8wt% in the condition of 293K/5MP工93K/6 0MPa and the ratio of desorption was 95 9% for the super activated carbon with the BET surface area of 3886m 2/g.
