Adsorption of benzene vapors in oil waste-based adsorbents

Abstract

The article studies the optimal conditions for obtaining effective adsorbents based on coke, adsorption of
benzene vapors on activated adsorbents. It was found that benzene vapors in the resulting adsorbents are
tightly bound by the formation of ~ 10% adsorbate π-complex in KA (coke-asphalt) during adsorptiondesorption.
Adsorption of benzene in KA is characterized by its excess compared to other adsorbents,
the presence of cracks in different layers of the adsorbent and high porosity compared to other adsorbents.
According to the results of adsorption of benzene vapors in adsorbents, these adsorbents can be used in
various fields, which makes it possible to some extent to satisfy the need of our Republic for adsorbents.
