| 中文摘要: |
| 使用经柠檬酸改性的Pt/SAPO-11催化废猪油一步加氢制备航空煤油。在单因素实验的基础上，采用响应面实验进行工艺优化，得到改性Pt/SAPO-11催化废猪油一步加氢制备航空煤油的最佳工艺条件为反应温度290.63 ℃、反应时间3.94 h、转速148.55 r/min、反应氢压3 MPa、油料比10∶ 1（废猪油与催化剂质量比），在此条件下C8～C16烷烃含量为71.34%，烷烃异构率为894%。产品经后续精馏等工序处理，可达到国标3号航空煤油标准。 |
| 英文摘要: |
| 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. |
