Key Points

This research aims to evaluate how bentonite adsorbent purifies used motor oils by changing their physicochemical properties.
Analyzed physicochemical properties before and after purification process.
Used bentonite as the primary adsorbent.
Assessed the reduction of impurities and oxidation products in treated oils.
Bentonite effectively removed mechanical impurities from used oils.
Significant reduction in oxidation products post-treatment.
Bleaching clay combined with bentonite showed enhanced purification effects.

Abstract

This article analyses the changes in the physicochemical properties of used oils that occur following an adsorption purification process using bentonite. According to the research results, the bleaching clay and bentonite adsorbent effectively absorbs mechanical impurities, oxidation products, and harmful additives
