| 中文摘要: |
| 以麻疯树籽油为原料，Pt/SAPO-11-mp为催化剂，通过单因素实验探究反应温度、反应压力、空速和氢油比（氢气与麻疯树籽油体积比，下同）对催化反应过程及航空燃料产物组分分布的影响。在单因素实验的基础上，以 C8～C16烃比率为响应值，利用响应面法优化了反应参数。结果表明：最优工艺参数为反应温度406.33?℃、反应压力4.3 MPa、空速1.2 h-1、氢油比1 049.71，在此条件下C8～C16烃比率为73.96%。对产品进行了理化性能的检测，结果显示，产品的密度、铜片腐蚀、运动黏度、冰点、总酸价、总热值等指标均达到了《3号喷气燃料》的指标要求。 |
| 英文摘要: |
| Using Jatropha seed oil as raw material and Pt/SAPO-11-mp as catalyst, the effects of reaction temperature, reaction pressure, space velocity and hydrogen-oil ratio （volume ratio of hydrogen to Jatropha seed oil, the same below） on the catalytic process and the composition distribution of aviation fuel products were explored by single factor experiment. On the basis of single factor experiment, the ratio of C8-C16 hydrocarbon was used as response value, and the response surface methodology was used to optimize reaction parameters. The results showed that the optimal reaction parameters were obtained as follows: reaction temperature 406.33?℃, reaction pressure 4.3 MPa, space velocity 1.2 h-1, hydrogen-oil ratio 1 049.71. Under these conditions, the ratio of C8-C16 hydrocarbon was 73.96%. The physicochemical properties of the product were also tested, and the results showed that the density, copper corrosion, kinematic viscosity, freezing point, total acid value and total calorific value of the product met the requirements of No. 3 Jet Fuel. |
