Currently in Brazil the minimum content of biodiesel in mixtures is 11% and,
according to Brazilian laws, the goal is to reach 15% in volume in diesel fuel available for final
consumers by 2023. Therefore, studies about different matrices of biodiesel and distinct mixtures
are essential. The present work had two goals, the first one was to analyse physico-chemical
properties of 16 biofuels produced from soybean and cotton oils, using S10 diesel, in mixtures
B8, B10, B20 and B30. The second goal was to verify the vantages and disadvantages of biodiesel
production through prior mixing of the oils, before and after the transesterification process. All
biofuels produced presented results of specific mass values at 20 °C and kinematic viscosity at
40 °C within the limits established by ANP Resolution no 30/2016 and International Resolutions.
The soybean B20 biofuel showed the best overall results, with the second highest production
yield of 65.36%, the fifth lowest kinematic viscosity with 3.48 mm s
-1
. The mixture of soybean
and cotton oils before the transesterification process presented the highest production yield when
compared with the production from a single oil or biodiesel mixtures. The results found proved
to be satisfactory and corroborate to continue with the increase of biodiesel in the mixture with
diesel to B15 until 2023 and support the possibility of planning for a gradual increase of this
mixture in the following years.
