Fluid-fluid phase equilibria in disordered porous media. Nonadditive hard sphere mixture

摘要

We report a computer simulation and integral equation study of fluid-fluid phase equilibria of nonadditive hard sphere binary mixture adsorbed in disordered hard sphere matrix. The mixture exhibits phase separation with critical density rho (f)(c) lower than its bulk counterpart. It is found that rho (f)(c) decreases with increasing both porosity and nonadditivity parameter. (C) 2001 Elsevier Science B.V. All rights reserved. [References: 35]
