Abstract
Solvent base oils of group API I contain larger quantities of aromatic compounds and sulfur, as compared to base oils of higher quality groups. Processing of base oils by commercial clays is performed in order to reduce the content of undesirable compounds, improving the color and oxidation stability. Commercial clays are based on aluminosilicates with a large specific surface area and developed porosity. Bentonite has good adsorption characteristics, which can be further improved by various methods of modification. In this paper, adsorption processing of solvent base oils is derived by acid-activated bentonite and commercial clay. The structural composition of starting oil and refined solvent oil (content of aromatics, paraffins, naphtenes and sulfur) is determined by following methods: IEC 590, UV, IP 346 and BAS ISO 20846. The results showed that processing of a solvent oil by activated bentonite leads to change of structural composition, similar to a change achived by processing wi...th commercial clay.
