摘要:

制备了负载Pd为活性金属,Al2O3与分子筛BEA组合为载体的催化剂Pd-Al2O3-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C8~C16烃的选择性的影响,并得到优化工艺参数。结果显示:对C8~C16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C8~C16烃类为73.86%。

Abstract:

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%.
