航空运输业的发展、石化能源的短缺以及环境污染问题，使生物航空煤油的制备得到了广泛关注。为了得到一步催化加氢制生物航空煤油的最佳工艺条件，本文以小桐子油为原料、Pd/ Hβ-Al2O3为催化剂，在高压反应釜中一步加氢制生物航空煤油。在单因素实验的基础上，利用 Box-Behnken 中心组合实验设计响应面法对工艺的反应条件（温度、氢压、转速）对C8～C16烃含量的影响进行了研究。结果表明：温度310℃、氢压2.48MPa、转速86.17r/min为最佳实验反应条件。在此条件下进行3次重复验证试验，脱氧率为99.98%，C8～C16烃的含量为73.86%。%The preparation of biological aviation kerosene has drawn great attention because of the development of air transport industry,the shortage of fossil energy and environmental pollution. To obtain the optimum conditions of preparing biological aviation kerosene by one-step catalytic hydrogenation,the biological aviation kerosene was produced by one-step hydro treatment over Pd/Hβ-Al2O3with jatropha oil as raw material in a high-pressure reactor. Based on single factor experiments,Box-Behnken central composite design of response surface methodology was applied to study the effect of the process conditions(temperature,hydrogen pressure,rotating speed)on the percentage of C8—C16 hydrocarbon. The experimental results show that the temperature of 310℃, hydrogen pressure of 2.48MPa,and the rotational speed of 86.17r/min were the best experimental reaction conditions. Under these conditions,the verification test was carried out 3 times,and the rate of deoxygenation was 99.98%,the percentage of C8—C16 hydrocarbons was 73.86%.
