摘要：

The kinetics of sorption of benzene and C6 ÷ C9n-paraffins into fairly large crystals of HZSM-5 and silicalite at 298 K were studied by gravimetry. The diffusivities characterizing the rates of sorption are listed. Diffusion of n-nonane is at least 102 times faster than that of benzene. The rate of sorption increases with decreasing length of n-paraffins; for n-hexane, it was already too high to be observed with precision. © 1990.
