ESTUDO DA PRODUÇÃO ENZIMÁTICA DE BIODIESEL A PARTIR DE ÓLEO RESIDUAL

This study aimed to the methyl biodiesel production by transesterification reaction via alkaline catalysis, using as a raw material alternative to soybean oil commonly used, coco-da-baia oil (Cocos nucifera L). The biodiesel was characterized as to its acidity, density, humidity, ester content, flash point, glycerol (free, total, mono-, di- and triglycerides) and maximum percentage of methanol. The oil used was characterized by acid value, saponification number, fatty acids, density and humidity. Through these results, we verified the quality of the obtained biofuel.
