Abstract : Flow rates of He, Ar, N2, Kr, methane, propane, and n-butane through a small circular cylinder of microporous 'saran' carbon at 25C were measured. The corresponding adsorption isotherms were also measured. The experimental results are reported. The observed flow rates of propane and butane are compared with those calculated by means of a theoretical equation deduced previously. The theoretical equation is based on a laminar viscous flow of liquid-like films and correlates flow rates with pore dimensions and adsorption isotherms. (Author)
