中文摘要	制备了孔分布相同比表面积不同、比表面积相同孔分布不同的系列超高比表面积（S〉2500m^2／g）活性炭，以天然气为吸附质研究了活性炭吸附剂比表面积及孔分布对天然气脱附性能的影响。结果表明：天然气脱附量随活性炭的比表面积及中孔百分率的增加而增加；在25℃、3．5MPa下，脱附量（V）与超高比表面积活性炭的比表面积（S）满足关系式：V=0．197S-78．0；脱附量与超高比表面积活性炭中孔百分率（X）满足关系式：V=2．18X＋3．24*10^2；活性炭的比表面积越大，脱附量受吸附压力及温度的影响越大；活性炭中孔百分率越大，脱附量受吸附压力的影响越大，而吸附温度对具有不同孔分布的活性炭脱附量的影响则具有一致性。
英文摘要	Activated carbons were prepared which provided wkh the same specific surface area and different pore size distribution or possess the same pore size distribution and different specific surface area. Natural gas was used as adsorbate to study the influence of the specific surface area and pore size distribution on the natural gas desorption amount. The experimental results showed that the desorption amount increase with the specific surface area or the percent of mesopore increment. The; relationship of desorption amount (V) and the specific surface area(S) accord with linear equation at 25 °C arid 3. 5 MPn- V~ 0. 197S-78. 0. The relationship of desorption amount(V) and the percent of mesopore (X) accord with function; V-2, 18X+ 3. 24X 102. At the same time, the desorption amount was affected more seriously by pressure or temperature with the activatedcarbons’ specific surface area enhancing. The desorption amount was affected more seriously by pressure for activated carbons with higher percent of equal to or greater than 2nm pore, and the influence of temperature on the desorption amount for activated carbons with the different pore size distribution was accordant. Meanwhile, the desorption amount based on voLume will be increased with the bulk density of activated carbons increasing.
