摘要：
Adsorption of methanol vapor on two activated carbons with different origins and activation, and two carbon fibers (ex-PAN and ex-rayon) were investigated in static conditions. An original approach for diffusion problems by combining data from isotherms and adsorption kinetics is presented. It is found that the adsorption kinetics are influenced by temperature, the surface chemistry, the mesoporosity and the microtexture of the pores (shape and size) of the samples studied.
