Abstract
Deoxygenation through decarboxylation of Jatropha curcas (non-edible) oil under a nitrogen atmosphere was performed using alumina (Puralox SBa200) and hydrotalcite (Pural MG70) as catalysts at 350 and 400 °C. In general, liquid product yields obtained exceeded 80%. FTIR spectroscopy showed that the oxygen contained in the liquid product decreases significantly when hydrotalcite is used as the catalyst with a reaction time of 6 h. At the end of the tests, a liquid biofuel was produced with a high proportion of hydrocarbons - around 83% - of mainly C8-C18. The product also showed good properties as a heating value of around 44 MJ/kg, higher than biodiesel (40 MJ/kg) and near to diesel (46 MJ/kg), and a lower viscosity (4 cSt) than biodiesel (4.5 cSt). Using GC analysis it was possible to identify the CO<inf>2</inf> and CO as the principal compounds present in the reaction gas, confirming that oxygen is removed mainly through decarboxylation and decarbonylation reactions.
