| Abstract: |
| With waste lard as raw material, biological aviation kerosene was prepared by one-step hydrogenation with Pt/SAPO-11 as catalyst in a high-pressure fixed bed catalyst reaction evaluation device.Based on single factor experiment, the preparation conditions of biological aviation kerosene from waste lard were optimized by response surface methodology. The results showed that the optimal preparation conditions were obtained as follows: reaction temperature 409.96?℃, pressure 5 MPa and hourly speed 1.24 h-1. Under these conditions, the C8-C16hydrocarbon isomerization rate was 34.58%.The result of regression equation showed that the simulated value was basically consistent with the actual value, and the model had certain significance. |
