Estudo comparativo das propriedades físico-químicas de biolubrificantes obtidos do óleo de soja refinado e residual.

Abstract

The use of fossil fuels has resulted in intense environmental impacts that raise the need to develop renewable energy sources. An excellent alternative is constant research into the development of energy sources and the production of goods that do not depend on fossil raw materials. The production of biolubricants from renewable raw materials is an example of these studies. Just as there is a concern with the scarcity of oil and the development of sustainable alternatives for energy production, there is currently another problem that affects everyone: pollution. Although residual cooking oil represents a tiny percentage of waste, its environmental impact is very large on the ecosystem. One of the methodologies for the synthesis of biolubricants is the transesterification reaction followed by the epoxidation of vegetable oil, improving the lubricating characteristics of the oil. This work consisted in the production of biolubricants from residual soybean oil, from a university restaurant on the Campus Cuité of the Federal University of Campina Grande, and the comparison with the biolubricant from commercial soybean oil. The materials involved in the process were characterized through their physicochemical properties. According to the results, the production of biodegradable lubricants can significantly help to reduce the environmental impact of the use of fossil materials for the production of lubricants, as well as the release of residual oil into the environment.
