Several recycling alternatives have been used around the world to recover the used lubricating oil. The process of solvent extraction is able to remove approximately 10-14% of contaminants, which corresponds approximately to the amount of additives and dross, typically found in used lubricating oil. This study had as objective to evaluate and optimize the recovery process of lubricating oils used in automotive diesel engines by polar solvent extraction (1-butanol, 2-propanol and methyl ethyl ketone) and clarification by natural clay, as well as characterizing physically and chemically the lubricating oil and clay samples, new, used, and recovered. The results allowed to conclude that the best extraction ranges are of 1: 6; 1: 4.7 and 1: 6 r...
