Abstract

We have studied unconventional types of raw sorption materials with a mixed composition: natural calcium aluminosilicates (zeolite-containing siliceous rocks) and iron aluminosilicates (zeolite-containing clays). It has been shown that mechanical processing of the raw materials under conditions of triboelectric formation of a gas–dust “plasma” allows the performance of sorbents to be improved, resulting in better structure and higher content of useful components (by 4–12%). After such processing, the sorbents have considerably better bleaching power for vegetable and diesel oil clarification: by 21–42% and by a factor of 1.2–5.8, respectively. The better properties of the sorbents are due to the changes in the characteristics of the starting aluminosilicates as a result of electrical size classification.

Keywords:
