摘要：

The two-component self-diffusion of C2H4 and C2H6 adsorbed in NaX zeolite crystals has been measured by H-1 pulsed field gradient (PFG) Fourier transform NMR. The results so obtained are compared with single-component self-diffusion measurements and with values for the intracrystalline mean residence times, determined by means of NMR tracer desorption experiments.
