Biodiesel de óleo de soja e sebo bovino: caracterização e avaliação das blendas

Abstract

Brazil is one of the largest soybean (Glycine max) and beef producer. Therefore, it is important to say that the main objective of the slaughter of the animal is meat production, but many by-products are created as well. Among them the beef tallow that has shown great potential of biodiesel production. Many companies have invested in their biofuel production plants, so they can process different raw materials greases, taking as example the biodiesels beef tallow, residual oil, fish oil, among other sources. On the other hand, soybean (Glycine max) is currently the most widely used raw material for biodiesel production in Brazil. The extracted vegetable oil from soybeans presents an important alternative for the production of fuel, especially considering the issues: environmental and economic, because biodiesel is virtually free of sulfur and aromatic compounds, emitting less particulate and soybeans is the main grain produced in the country. In this context, this paper’s goal is related to production and characterization of polymer blends of biodiesel from soybean oil and beef tallow, using compliance standard parameters adopted by the Petroleum National Agency (ANP), according to ANP Resolution No. 45 of 25.08.2014. Based on the results, soybean biodiesel blends (BSJ), beef tallow biodiesel (BSB), in the proportions 25/75, 50/50, 75/25 (BSB/BSJ) showed the best results for density, moisture content, viscosity and oxidative stability.
