| Abstract: |
| Aviation kerosene was prepared by one-step hydrogenation of waste lard catalyzed by citric acid modified Pt/SAPO-11. On the basis of single factor experiment, the preparation conditions of aviation kerosene from waste lard catalyzed by modified Pt/SAPO-11 were optimized by response surface methodology as follows: reaction temperature 290.63 ℃, reaction time 3.94 h, speed 148.55 r/min,reaction hydrogen pressure 3 MPa and mass ratio of waste lard to modified Pt/SAPO-11 10∶ 1.Under the optimal conditions,the content of C8-C16 alkanes was 71.34% and the alkanes isomerism rate was 894%. The product could meet the national standard of No.3 aviation kerosene after subsequent rectification and other processes. |
