Conclusions

  1. 1.

    An analysis was made of the kinetic factors and longitudinal transport on the basis of experimental data on the dynamics of the adsorption of benzene and developing chromatography of helium, argon, and nitrogen for layers of narrow fractions of activated charcoals and adsorption-inert glass of various grain sizes within a broad range of specific velocities.

  2. 2.

    Within the range of experimental parameters studied, the length of the working layer of charcoal (length of the zone of mass transfer) for the stationary stage of the dynamics of adsorption of benzene is determined chiefly by longitudinal transport and internal diffusion of the adsorbed substance. External diffusion may play an appreciable role only for charcoal with small grain size. The thermal effect of physical adsorption has no influence on the dynamics of adsorption within the limits of the experimental error.
