| Abstract: |
| 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. |
