Kinetic measurements were made of the intracrystalline sorption of trans-2-butene and the resulting deformation of granulated NaA zeolite with crystal radii of 1.19, 5, 9 and 12μm. It was shown that the rates of sorption and deformation essentially coincided. From the linear dependence of the first statistical moment of the kinetic curves of sorption and deformation on the square of the crystal radius, the coefficient of intra-crystalline diffusion of trans-2-butene in granulated NaA zeolite was determined to be 1 x·10-16m2/s.
