The catalyst loaded with Pd as an active metal and combined Al2O3 and molecular sieve BEA as carrier was prepared, and it was used to catalyze the one-step hydrogenation of Jatropha oil in a high-pressure reactor to produce aviation kerosene. On the basis of single factor experiments, the Box-Behnken central combined experimental design response surface method was used to optimize the process parameters (reaction temperature, pressure, speed) with the deoxygenation rate of fatty acids in Jatropha oil and the selectivity of C8-C16 hydrocarbons as indexes. The results showed that the effect order of the C8-C16 selectivity was reaction temperature>speed>pressure, and the optimal reaction conditions were 310 ℃, pressure 2.48 MPa, and rotating speed 90 r/min. Under these condition, total hydrocarbons in aviation kerosene contained 99.98%, of which C8-C16 hydrocarbons was 73.86%.
