Resumo: Biodiesel has been obtained from methanolysis of buriti oil. This biodiesel was added in fossil diesel in order to obtain diesel/biodiesel blends. Thermal analysis of blends were carried on 30-600oC range at rate of 10oC min.-1. Kinetic parameters such as activation energy (Ea), pre-exponential factor (A), Gibbs energy (Δ≠G), enthalpy (Δ≠H) and entropy (Δ≠S) of activation were determined by using Coats–Redfern equation. The Ea, Δ≠H and Δ≠G values presented a linear increase with biodiesel amount added in blends. The heat of combustion of diesel/biodiesel blends was determined, and it was observed that the heat of combustion decreased with the addition of biodiesel in diesel/biodiesel blends.
