抄録

In this work, an effect of anion (Br^-, CI^- and F^-) of tetra-n-butyl ammonium (TBA) salts on the H_2 and CO_2 adsorption and diffusional characteristics of semi-clathrate hydrate was investigated with multiple adsorption resistance (MAR) model for the purpose of gas separation. The equilibrium H_2 occupancy in the S-cage depended on the semi-clathrate hydrate structure. The equilibrium CO_2 occupancy in S-cage depended not only on that but also on the TBA salt for TS-I strucure. The apparent diffusion coefficients for H_2 systems were larger than those for CO_2 systems. The H_2/CO_2 selectivities for 3.0 mol% TBAF semi-clathrate hydrate was the highest among TBA salt semi-clathrate hydrate.
