Popis:	The kinetics of sorption in most commercial adsorbents (e.g. charcoals or zeolites) results from the interaction of several distinct steps of mass transfer. In order to understand and analyse the compound kinetics it is expedient to design experiments so that the rate of individual steps can be observed independently. Otherwise, the rate of diffusion in micropores or in cavities of zeolite crystals is likely to be obscured by resistance to mass transfer in intercrystalline voids of the sample or in the macropores of a pellet. Temperature excursion in the solid sorbent owing to exothermicity of sorption can be controlled through direct contact of the solid sorbent with a heat sink of sufficient capacity. Results obtained for hydrocarbons in zeolite ZSM-5 are briefly reported.
