Abstract

This work covered the following aspects:

1.1 Study of the fundamentals of recycling burned lubricating oils using acid-clay treatment.

1.2 Removal of water from burned oil using simple vacuum distillation.

1.3 Recycling of burned lubricating oil by treatment with 98% sulfuric acid. (1) (2)

1.4 Filtration of this oil through different clay concentrations (8%, 10%, and 12% relative to the volume of oil to be filtered). (3)

1.5 Determination of the physicochemical properties of both the lubricating oil obtained after distillation and the oils obtained after filtration with varying clay percentages.

1.6 The following were determined: density, acidity, viscosity, sulfated ash, and moisture. (4) (5)

1.7 The efficiency of each stage of recycling burned lubricating oil was also calculated.

This work was conducted to determine whether it is feasible to recycle burned lubricating oil for reuse at the industrial level or in internal combustion engines. The results demonstrated, with 95% certainty, that there was an improvement in the physicochemical properties after the recycling treatment.

Through statistical analysis, we can determine that the improvement was determined to a greater extent when 12% of clay was used to filter the oil.
