Metal oxide promoted ceria-zirconia (Ce/Zr = 6/4) catalysts was applied to deoxygenation (DO) of oleic acid in batch mode at 300℃ under 1 bar of 20% H2/N2 condition. Metal oxide promoted ceria-zirconia catalysts were prepared by a co-precipitation method. As a result, Ni-Ce0.6Zr0.4O2 catalyst exhibited much higher oleic acid conversion, selectivity to C9 ~ C17 compounds (diesel fuel range), and oxygen removal efficiency than the others. This is due to the presence of free NiO species, synergy effect of nickel and Ce0.6Zr0.4O2, highest BET surface area, and the strong metal to support interaction (SMSI).
