摘　　要：制备了负载Pd为活性金属,Al_(2)O_(3)与分子筛BEA组合为载体的催化剂Pd-Al_(2)O_(3)-BEA,在高压反应釜中以其催化麻疯树油一步加氢制备航空煤油。在单因素试验的基础上,利用Box-Behnken中心组合实验设计响应面法考察反应温度、压力、转速对麻疯树油中的脂肪酸的脱氧率和C_(8)~C_(16)烃的选择性的影响,并得到优化工艺参数。结果显示:对C_(8)~C_(16)的选择性影响顺序为反应温度>反应转速>反应压力,较佳反应条件为反应温度310℃,压力2.48 MPa,转速90 r/min,此条件下航空煤油中总烃类含99.98%,其中C_(8)~C_(16)烃类为73.86%。The catalyst loaded with Pd as an active metal and combined Al_(2)O_(3) 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 C_(8)-C_(16) hydrocarbons as indexes.The results showed that the effect order of the C_(8)-C_(16) 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 C_(8)-C_(16) hydrocarbons was 73.86%.
