Abstract

Ce_(1-x)Zr_(x)O₂ catalysts were prepared by co-precipitation method for deoxygenation (DO) of oleic acid. The CeO₂/ZrO₂ ratio was systematically varied to optimize Ce_(1-x)Zr_(x)O₂ catalysts. Ce_0.6Zr_0.4O₂ exhibited the highest oleic acid conversion as well as high selectivity to C₉~C₁₇ compounds (diesel fuel range) at the reaction temperature of 300°C. The high activity/selectivity of Ce_0.6Zr_0.4O₂ catalyst was correlated to its reducibility, oxygen storage capacity and crystallite size.
