With the annual increase in the demand for energy in different sectors of activity, mainly from fossil resources, there is growing concern about the generation of polluting gases with a great impact on the environment (global warming, among others) and public health. Therefore, technological solutions are sought that meet the requirements of increased efficiency and decarbonization. One answer to this problem is renewable energy sources: in the transport sector; biofuels are increasingly widespread. In particular, in some countries such as Brazil, the practice of using biofuels mixed with fossil resources (biodiesel in diesel oil and ethanol in gasoline) is mandatory by law. Therefore, the search for innovations in response to this demand arises, and from studies and research, new fuels are developed. As in the case of HVO, or green diesel, which can be produced with some of the same raw materials as ester-based biodiesel, such as vegetable oils and animal fat, however, HVO is produced by a more modern process, called hydrogenation, which confers different fuel properties. For this reason, studies comparing the benefits of different blends between these fuels are necessary to achieve the best properties following local regulations. In this work, theoretical properties were calculated for ternary mixtures composed of diesel oil, biodiesel and HVO, such as boiling point, flash point, cetane number, density, kinematic viscosity, cloud point, pour point, lower calorific value, CO2 equivalent emissions over the entire life cycle and production costs per unit of energy in the fuel. Ternary diagrams were created in MATLAB software, with the objective of optimizing the composition of the ternary mixture to simultaneously meet technical, economic and environmental requirements through the use of desirability functions. As a result, a mixture of 53,6 per cent of diesel oil, 24,1 per cent of biodiesel and 22,3 per cent of HVO was obtained, which generated a reduction in CO2 equivalent emissions of 7,1 per cent with an increase in cost of 15,4 per cent, compared to B12 diesel.
