Dual diffusion and finite mass exchange model for adsorption kinetics in activated carbon

“…For each species, adsorption isotherms at several temperatures ( 2 3) were measured . The single component adsorption/desorption kinetics on Ajax carbon were measured on a differential adsorber bed rig (DAB), under various conditions such as different temperatures, pellet length/geometry and bulk concentrations (Do, 1997). High purity nitrogen is used as the…”

“…diluting gas in the bulk phase. The detailed setup of volumetric and DAB rigs as well as their related experimental procedures are also described in Do (1997).…”

“…If a mathematical model is to carry its useful role in simulating or predicting adsorption/desorption in activated carbon, it must be able to describe the following facts which have been observed experimentally in a large number of experiments (Do, 1997):…”
