Ce(1-x)Zr(x)O2 catalysts were investigated for bio-diesel production from oleic acid using catalytic deoxygenation. In this study, deoxygenation reaction has been carried out at 300 oC under 1 bar of 20% H2/N2 pressure in batch mode. Ce(1-x)Zr(x)O2 catalysts were prepared by co-precipitation method. Ce0.6Zr0.4O2 catalyst showed the highest oleic acid conversion and C9~C17 selectivity. It has been found that the deoxygenation reaction depends strongly on the reduction property and depends partly on the crystallite size of Ce(1-x)Zr(x)O2. Thus, Ce0.6Zr0.4O2 can be selected as the most promising catalyst for deoxygenation reaction.
