Monitoring of the Physico-Chemical Quality of a Frying Oil and its Valorization as Biofuel (Biodiesel)

Abstract

The production of biofuels such as biodiesel has attracted considerable attention as a cleaner source of renewable energy, which can greatly contribute to reducing our dependence on fossil fuels.           In this study, we were interested in the production of a biofuel based on non-food used frying oil, and 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 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.
