| 摘 要： | 为了探究煤直接液化油提质转化制备航空航天燃料的适宜生产工艺,以神华煤直接液化油为原料,针对其硫含量较高、氧含量高、不饱和度大等特点,提出了"碱洗提酚-加氢脱硫-加氢饱和"的工艺流程。采用自主研发的NiMoW/Al2O3和Pd/Al2O3催化剂,通过固定床加氢的方法,对脱硫和饱和生产工艺条件进行了研究。实验结果表明加氢脱硫最适宜反应条件为5 MPa,300℃,加氢饱和的最适宜反应条件为4 MPa,210℃。所得产物油具有较高的密度和净热值,耐热温度可达550℃且具有很好的热氧化安定性,具有作为优质航空航天燃料的潜质。

| Abstract: | In this study,the suitable process conditions for upgrading coal-derived oil for aerospace application have been explored.Shenhua coal direct liquefaction oil was used as the raw material.Due to the characteristics of high sulfur content,high oxygen content,and large unsaturation,a process of"alkali washing-hydrodesulfurization-hydrogenation saturation"was employed.Using the self-developed catalysts(NiMoW/Al2O3 and Pd/Al2O3),the optimal reaction conditions were determined to be5 MPa and 300℃for hydrodesulfurization,and 4 MPa and 210℃for hydrosaturation.The as-prepared product oil possessed high density and high net heat value.The as-prepared fuel also exhibited high withstanding temperature of 550℃and good thermal oxidation stability. |
