ヘンリー型吸着等温線を持つ銀ゼオライトによるヨウド・ブタンの回分槽吸着

Adsorption of 1-iodo-butane in n-dodecane on silver zeolite (of lonex Research Corp., U.S.A.) was carried out in a batch tank at 50, 60 and 70°C. The adsorbate bulk Concentration-time data measured at various times before the equilibrium reached gave the values of surface diffusivity, particle-fluid mass transfer coefficient and the Henry's adsorption equilibrium constant. The mass transfer coefficient was found to be in terms of Sherwood number from 2-∞, i.e., the same theoretical curve which agreed with the measured data was predicted with any Sherwood number greater than two. This indicated that the adsorption was controlled by the mass transfer within the adsorbent particle. The adsorption equilibrium constant and surface diffusivity were, respectively, expressed by the Arrhenius type equations.
