A semi‐empirical method is proposed for the prediction of adsorption equilibria of binary gas mixtures from pure component isotherms, including and extending beyond the range of validity of previous methods. It is based on an expression, derived earlier by one of the authors(1) which relates the binary separation factor α to the pure component pressure ratio at constant volume adsorbed. The method permits the quantitative calculation of the binary isotherms, V 1 = f 1 ( p 1 ) and V 2 = f 2 ( p 2 ), in the entire range of mono‐molecular adsorption, and yields predicted values in good agreement with experimental data for a variety of systems in the range 75°‐363°K and total pressures up to 35 atm.
