The production of high grade jet fuels from vegetable oils is an issue of special interest to refineries. The
conversion process involved hydrotreating (i.e. hydrodeoxygenation and hydrodecarboxylation) of the
oils followed by subsequent hydroisomerization. The paper reviewed recent literature on the role of
heterogeneous catalysts in the various processes. Catalysts based on Ni and Mo supported on oxides are
considered very active for the hydrotreating process whereas Pd and Pt supported on zeolites as the main
hydroisomerization catalysts. However, further studies are still required on the role of catalyst topology,
reaction mechanisms and the strategies for mitigating catalyst deactivation
