Abstract

In this study, a series of Ni−Ce 0.6 Zr 0.4 O 2 catalysts, which were synthesized by co-precipitation followed by calcination at different temperatures, were applied for the deoxygenation of oleic acid. The physicochemical properties of the catalysts were characterized by N 2 adsorption-desorption, X-ray diffraction (XRD), H 2 chemisorption, H 2 temperature-programmed reduction (H 2 -TPR), NH 3 temperature-programmed desorption (NH 3 -TPD), and X-ray photoelectron spectroscopy (XPS). The Ni−Ce 0.6 Zr 0.4 O 2 catalyst calcined at 300 °C exhibited the highest conversion for oleic acid as well as selectivity for diesel-range compounds. It is predominantly related to the highest amount of free NiO species. In addition, the acidity of the catalyst significantly affected the selectivity and distribution of products.
