用以石油焦为原料、ＫＯＨ为活化剂制得的高比表面积活性炭作为吸附剂，研究了甲烷在这种吸附剂上的脱附行为，探讨了活性炭的ＢＥＴ比表面积和孔结构与甲烷脱附性能的关系以及脱附温度和脱附时间对甲烷脱附行为的影响。结果发现：在这种高比表面积活性炭上，甲烷存在着明显的不可逆吸附；活性炭的比表面积和孔结构对甲烷的脱附性能有一定影响，并且随着脱附温度的升高和脱附时间的延长，脱附量逐渐增多
The desorption behavior of methane on this adsorbent was studied with high specific surface area activated carbon prepared from petroleum coke as raw material and KOH as activator. The BET specific surface area, pore structure and methane desorption The relationship between performance and desorption temperature and desorption time on the desorption behavior of methane. The results showed that there was a significant irreversible adsorption of methane on the surface of activated carbon with high specific surface area. The specific surface area and pore structure of activated carbon had certain influence on the desorption of methane. With the increase of desorption temperature and the desorption time Extended, desorption gradually increased
