摘要
Adsorption equilibria of binary gas mixtures on rigid solid adsorbents like activated carbons (AC) and molecular sieves (MS) can be measured "on line" by combining the (well known) gravimetric and the volumetric method. The resulting volume-gravimetric method is described. Also the basic equations necessary to calculate the masses of each of the two adsorbed components are formulated. Explicit solutions for binary ideal gas adsorptives are given. The experimental device used for measurement is outlined. Data for coadsorption equilibria of a N2/CH4 mixture on activated carbon AK WS IV-G 20575 at T = 298 K in the pressure range 1-20 bar are reported and discussed to a certain extend.
