【 摘 要 】

References(2)Cited-By(13)Equilibrium data for single-component adsorption on activated fiber carbon, KF-1500 are presented for the five gases methane, ethane, propylene, 1-pentane and carbon dioxide at 0, 25 and 50 °C. An adsorption equation by a multi-site occupancy model for homogeneous surface represents the isotherms fairly well, but the calculated amounts of adsorption are usually less than those observed at low surface coverage. The deviation may be attributed to the surface heterogeneity, which is neglected in the equation. From a comparison of isotherms on glanular and fiber activated carbons, it is suggested that the difference is only in the specific surface area, and that the other two parameters, the number of sites occupied by a molecule and the adsorption equilibrium constant, are almost the same for the two activated carbons.
