✦ Synopsis

METHOD, RESULTS, AND DISCUSSION It is shown that the known Dubinin-Radushkevich (DR) equation, which is widely used in engineering calculations of different Among adsorption processes is physical adsorption caused technological processes and, in particular, in the field of chemical by dispersion interactions. For carbon adsorbents, a deprotection, follows from an earlier equation representing the intermining component of adsorption interactions is the disperterphase equilibrium condition for certain model prerequisites. A sion force. An increase of the adsorption energy in microphysical justification of the DR equation and its refinement is pores is one of the main causes of an increase in the adsorppresented. ᭧ 1998 Academic Press tivity of microporous adsorbents compared to that of Key Words: adsorption; microporous adsorbents; theory of adrelatively macroporous or nonporous adsorbents of the same sorption; the Dubinin-Radushkevich equation. chemical nature (2).
