Adsorption phenomena of gas in solids are investigated using the Ono-Kondo lattice model. Layer concentrations rho(n) (n = 1, 2,... L) and Gibbs adsorption Gamma are presented versus the bulk density rho(b) and temperature. It is found that the density in core region (inner layers) and the density of the first layers next to the walls exhibit an opposite temperature dependence: while the density near the walls increases with decreasing temperature the density of the core region decreases to reach rho(b) as T increases. The density profile of the layers is also presented.

Abstract

Adsorption phenomena of gas in solids are investigated using the Ono-Kondo lattice model. Layer concentrations rho(n) (n = 1, 2,... L) and Gibbs adsorption Gamma are presented versus the bulk density rho(b) and temperature. It is found that the density in core region (inner layers) and the density of the first layers next to the walls exhibit an opposite temperature dependence: while the density near the walls increases with decreasing temperature the density of the core region decreases to reach rho(b) as T increases. The density profile of the layers is also presented.
