Biodiesel a partir do óleo de fritura residual e gordura animal (sebo bovino)

Abstract

Biodiesel is a fuel obtained from the transesterification of vegetable oils or animal fats. In this work, the biodiesel was obtained by transesterification of frying oil residual, animal fat (tallow beef) and their mixtures in different proportions. The reaction was done using an alcohol (methanol) in the presence of a basic catalyst (KOH) at the temperature of 50°C for 60 minutes. The biodiesel was characterized by the index of acidity, specific mass at 20°C, corrosive to copper and kinematic viscosity. The physical and chemical analyzes show that biodiesel obtained 100% of beef tallow was what showed the best results in all the analyzed requirements , the same fits in standard required by ANP (Resolution no. 45, 2014). The tallow that would otherwise be discarded and lost presents a low cost when compared to other raw materials for the production of biodiesel, the frying oil residual by its time also offers a low cost and can be used for the production of soap and other products derived from glycerin, which would previously discarded. Although raw materials for easy access and that your discard improperly can generate several problems to the environment, a viable solution would be the production of biodiesel, which would generate income and sustainability.
