Determination of the Kinetics and Thermodynamics Parameters of Biodiesel Oxidation Reaction Obtained from an Optimized Mixture of Vegetable Oil and Animal Fat
Diego Galvan,Juliane Resges Orives,Rodolfo Lopes Coppo,Elisângela Tavares da Silva,Karina Gomes Angilelli,Dionísio Borsato +5 more
TL;DR: The temperature influence on the oxidation stability of biodiesel from ternary mixture of vegetable oil and animal fat (50% of soybean oil, 20% of beef tallow, and 30% of poultry fat) was evaluated at temperatures ranging from 110 to 130 °C applying the Arrhenius and Eyring equations.
