Abstract
Ni-loaded Ce0.6Zr0.4O2 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-Ce0.6Zr0.4O2 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-Ce0.6Zr0.4O2 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).
