Abstract

Ni-loaded Ce_0.6Zr_0.4O₂ catalysts were prepared by a co-precipitation method and subsequently employed in the deoxygenation of oleic acid under solvent-free conditions. Among the prepared catalysts, the 20 wt% Ni-Ce_0.6Zr_0.4O₂ catalyst exhibited the highest catalytic activity, i.e., 98.3% oleic acid conversion, with 33.9% C₉-C₁₇ selectivity, and a 95.7% oxygen removal rate. The basic fuel properties of the obtained products were then examined to determine their potential for use in a diesel engine. The product produced using the 20 wt% Ni-Ce_0.6Zr_0.4O₂ catalyst exhibited a particularly high calorific value (i.e., 10213 cal/g, similar to that of commercial diesel, i.e., 10220 cal/g), the lowest viscosity (25.2cP), and the lowest solidification temperature (−15 °C).
