摘　　要：以石油焦为原料、KOH为活化剂制得超高比表面积活性炭吸附剂并用于H2吸附储存,采用BET和SEM对其结构进行了表征。结果表明,该吸附剂具有发达的微孔结构且其比表面积高达2693 m2/g,其孔结构以狭缝状孔结构为主。该吸附剂具有高的H2吸附储存能力,在吸附压力为9.0 MPa、吸附温度为273K时,H2脱附量可达12.21 mmol.g-1。A super-high specific surface area activated carbon was prepared from the petrol coke with KOH as activator, and its performance as the adsorbent for hydrogen storage was studied. The structure properties of the prepared activated carbon were characterized by BET and SEM. The results indicated that the activated carbon had high specific surface area of 2693m2/g, developed micropore structure, which was dominantly slit shape, and high hydrogen storage capacity. The hydrogen desorption quantity could reach 12.21 mmol.g-1 when the adsorption pressure and temperature were 9.0 MPa and 273 K, respectively.
