摘要：

Adsorption equilibrium data for CO(2) and N(2) On coal-based activated carbon were obtained at 323.15, 348.15, 363.15 K and at partial pressures from 100 Pa to 82425 Pa by a volumetric apparatus. Lower temperature is helpful for the adsorption. It was observed the saturation loadings at 323.15 K are 0.3 mmolg(-1), 0.057mmolg(-1) for CO(2) and N(2), respectively. The Langmuir and Sips equations were used to correlate the experimental data. It was found that the Sips equation is more accurate to describe the adsorption behavior of both gases on activated carbon. Henry's constant was calculated, it proves that activated carbon has a high selectivity on CO(2) than N(2), the maximum separation index is 5.5.
