Produção de biodiesel a partir de óleo de fritura residual

Abstract

In this work we used residual soybean oil (frying) for biodiesel production. Chose to transesterified with homogeneous catalyst (NaOH), for being the most used nowadays. For a better formulation was used a factorial design 2 ³, as variables catalyst concentration, molar ratio alcohol: oil and temperature. The goal was to produce biodiesel with an acceptable yield and quality, enabling it to use as fuel, according to the standards specified by the national oil agency. Obtained a sample of six biodiesel being the best yield of 73.9%.
