Diffusion of linear alkanes in 5A zeolite crystals has been studied by several different experimental techniques. In the range C3–C8 the diffusivity decreases regularly with carbon number (with a corresponding increase in activation energy) and there is good agreement between ZLC values and the data provided by the “microscopic” techniques (PFG NMR and Quasi-Elastic Neutron Scattering). At higher...
