Abstract

Bio-jet fuel range alkanes were prepared by catalytic deoxygenation reaction of non-edible acid oils with no added hydrogen. A WOx[6]/Pt[1.6]/TiO₂ was used for the deoxygenation of stearic acid and Jatropha fatty acid derived from Jatropha oil by hydrolysis. Tungsten addition to the Pt/TiO₂ showed remarkably enhanced performance, a degree of deoxygenation of 86%, which is more than two times higher than that of the Pt/TiO₂, even though the WOx/TiO₂ had almost no activity for deoxygenation reaction. The enhanced Pt-related hydrogen uptake, measured by H₂-TPR, and XPS analysis showed the intimate contact of tungsten with Pt nanoparticles supported on TiO₂. This tight contact allows for easier C–C cleavage over Pt nanoparticles and this is assisted by the strong bonding between tungsten and oxygen in the reactant, resulting in more C₁₇ hydrocarbon production on the WOx/Pt/TiO₂.
