| 中文摘要: |
| 以麻疯树油为原料，在Pt/SAPO-11双功能催化剂作用下一步加氢制备生物航空煤油，考察了不同反应温度、空速、压力和氢油比对产物脱氧率、C8～C16比率及C8～C16烃异构率的影响。结果表明：高温、高压会促进二次裂化反应的发生，使C8～C16比率下降；空速增大导致平均停留时间缩短，使脱氧率下降。综合考虑脱氧率、C8～C16比率及C8～C16烃异构率指标得到最佳工艺条件为反应温度670 K、空速1.2 h-1、压力5 MPa、氢油比1 000∶?1，在此条件下脱氧率为99.24%，C8～C16比率为71.16%，C8～C16烃异构率为37.92%。该研究为新能源的开发及其在航空领域的应用提供了理论依据。 |
| 英文摘要: |
| With Jatropha curcas oil as raw material, biological aviation kerosene was prepared by one-step hydrogenation with Pt/SAPO-11 as catalyst. The effects of reaction temperature, hourly speed, pressure and ratio of hydrogen to oil on deoxidation rate, C8-C16 ratio and C8-C16 hydrocarbon isomerization rate of the product were studied. The results showed that the high temperature and high pressure could promote the occurrence of secondary cracking reaction, so C8-C16 ratio decreased. The increase of hourly speed led to the reduction of average residence time, resulting in the decrease of deoxidation rate. Considering the deoxidation rate, C8-C16 ratio and C8-C16 hydrocarbon isomerization rate, the optimal preparation conditions were obtained as follows: reaction temperature 670 K, hourly speed 1.2 h-1, pressure 5 MPa and ratio of hydrogen to oil 1 000∶?1. Under these conditions, the deoxidation rate, C8-C16 ratio and C8-C16 hydrocarbon isomerization rate were 99.24%, 71.16% and 37.92% respectively. It provided a theoretical basis for the development of new energy sources and its application in the field of aviation. |
