Abstract: This paper deals with a theoretical and experimental investigation of adsorption kinetics. The adsorption on molecular sieve Calsit 5 of n-heptane from a nitrogen stream is studied experimentally in a differential bed. The influence of particle size, gas inlet concentration and temperature and linear gas velocity is investigated. The mass transfer rate is calculated theoretically by means of three various models. A comparison between theory and experiments allows to determine both the apparent pore diffusivity and the apparent surface diffusivity. The results presented in this paper provide evidence for the existence of surface diffusion.
