Reciclagem de óleo lubrificante usados em motores diesel utilizando butan-1-OL.

Abstract

The lubricating base oils are mineral or synthetic substances responsible for the formation of a protective film, which prevents direct contact between two surfaces that move relative to each other. The lubricant mixture is formed by the junction of additives to the base oil obtained from the distillation of petroleum. Where waste oil are released directly into the environment or when burned in an uncontrolled way, causing serious soil pollution problems, water and air. Recycling the lubricant applying means physicochemical processes on the oil used, making possible to obtain the base oil, the raw material can be reused to obtain lubricants. The aim of this study was to evaluate the process of recycling of automotive lubricating oils used in diesel engines through extraction by polar solvent, butan-l-ol. Chemical and physicochemical properties of lubricating oils as compared with the recycled and new lubricating oil lubricating oils were evaluated. If we look at the dangers that used oil can cause to the environment, a possible solution to the difficulties encountered was proposed in this paper.
