ADSORPTION OF GASES AND STEAMS ONTO A SUI TE OF COMMERCIAL ACTIVATED CARBONS

The adsorption isotherms of 10 different adsorptives have been measure d at different temperatures over a large relative pressure range onto a suite of commercial activated carbons with different extents of acti vation. The experimental results were evaluated by means of BET, Arano vich and Dubinin equations. Micropore distribution functions were calc ulated by use of the Jaroniec-Choma model and regularization method. T he obtained parameters and pore size distributions showed significant dependences between the microporosity of the samples and the level of activation. The micropore distribution functions calculated by use of regularization method point out to problems of the DR-equation as loca l isotherm.
