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8.94%。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。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 was8. 94%. The product could meet the national standard of No. 3 aviation kerosene after subsequent rectification and other processes.
