local.description.resumoConventional biofuels, as biodiesel and bioethanol, are oxygenated compounds that have different physical-chemical properties when compared to fossil fuels. Otherwise, drop-in biofuels are bio-hydrocarbons that have the same chemical composition of fossil fuels. These oxygen-free fuels can be used without changes in structure that already exists to fossils fuels, as engines, turbines and tanks. This work presents the synthesis of bio-hydrocarbons via deoxygenation over Co/C catalyst using Macauba acid oil as feedstock. It is an inedible oil, with high acidity (about 38%) from a perennial palm tree with high oil productivity. Macauba endocarp activated carbon supported cobalt catalyst was synthesized and tested in order to develop a low cost and sustainable conversion route. Degree of deoxygenation of 98.4 %wt was achieved using Macauba pulp oil as feedstock, 10 wt% of catalyst, at temperature of 350 °C, pressure of 30 bar H2 for 4 h. The synthesized bio-hydrocarbons presented carbon chains equivalent to the fractions of gasoline, aviation kerosene and, mostly, diesel. These drop-in biofuels and the innovative catalyst appear as an important alternative for transport sector and for improving the sustainability of Macauba biorefinery.
