THE INVESTIGATION OF SORBTION CAPACITY OF SUBSTITUTED FORMS OF SAPONITE CLAYS

Abstract

The influence of the process of modification of saponite clays with salts of monovalent cations, its granulation and sorption properties of the obtained granular aluminosilicates are investigated. It is established that the modification mode and granulation parameters retain the sorption characteristics of natural smectite minerals in relation to hydrocarbon mixtures. It is shown that solving the problem of choosing the method and conditions of modification and granulation will allow to obtain mechanically robust and chemically stable materials, which should be used as a filter load for purification of petroleum products and for their dewaxing. Saponite clay samples were evaluated by SEM microscopy, X-ray phase and X-ray fluorescence analyzes. Moreover, IR spectroscopy was performed.
