Conclusions

  1. 1.

    The porous structure and adsorption properties with respect to benzene vapors of a number of characteristic samples of activated charcoals was studied.

  2. 2.

    The procedure was described and an investigation was made of the dynamics of the adsorption of benzene on activated charcoals with various porous structures and grain sizes, at various linear rates of flow.

  3. 3.

    The experimental results correspond to a system of parallel transport of the adsorption wave. The lengths of the working layers of activated charcoals, with all other conditions constant, decrease substantially with decreasing volume and surface of the transport pores, which is an indirect indication of a substantial role of internal diffusion transport in the kinetics of adsorption.
