Abstract

Over the past three decades, biodiesel has experienced remarkable development. This fuel, obtained from vegetable oils or animal fat, has the advantage of being renewable, less polluting, and reduces the energy dependence of oil-importing countries.In this article, we are interested in the production of a biofuel based on non-food used frying oil. The physico-chemical characteristics for Oleor vegetable oil are found to comply with established standards. After subjecting the oil to repeated frying using potatoes, followed by a physico- chemical evaluation, the results obtained showed the thermo- oxidative alteration of this oil, confirmed by the evolution of the physico-chemical indices. chemicals during frying. At the end, this used oil is recovered as fuel (biodiesel). The production of biodiesel is obtained by the transesterification reaction, with a conversion rate of 85%. The physico-chemical properties determined are very interesting and close to those of commercial diesel.
