摘要/Abstract

摘要： SRH柴油液相循环加氢技术是利用油品中的溶解氢来满足加氢反应的需要，以油品中氢浓度的梯度变化作为反应的推动力。该技术催化剂床层处于全液相中、接近等温操作，反应效率高、目的产品收率高；整套装置高压设备少，热量损失小，装置投资和操作费用均低。中型装置试验结果证明，SRH液相循环加氢技术可以在适宜的工艺条件下加工各种柴油原料，对原料适应性强、产品质量好。长岭20万吨／年SRH液相循环加氢装置工业应用结果表明：以煤油为原料可以生产合格的3^#喷气燃料；以常二柴油、催化柴油和常二柴油、焦化柴油的混合油为原料可以生产满足国Ⅲ质量标准的清洁柴油；以常二线柴油为原料，可以生产满足欧Ⅳ质量标准的清洁柴油，同时该装置长期稳定生产运行表明SRH液相循环加氢技术和关键设备成熟可靠。

Abstract: SRH liquid phase recycling hydrogenation technology takes the advantages of hydrogen，dissolved in liquid phase，to meet the hydrogenation reaction requirements，in which hydrogen concentration grads in the oil can act as the driving force for the reaction. SRH technology is characterized by its catalyst bed fully submersed in the liquid phase and close to isotherm operation as well as its high reaction efficiency and high target product yield. In addition，both the unit investment and operating costs are lower because of fewer high pressure devices adopted and less heat loss. The pilot plant results showed that SRH technology had strong adaptability to feed and can be applied to process different diesel under suitable process conditions. The products were also with good quality. Besides，the commercial application results from SRH diesel phase liquid recycling hydrogenation unit with capacity of 20×10⁴t/a in Chang-ling Refinery showed that：qualified 3^# jet fuel can be produced using kerosene as feed；clean diesel with meeting national Ⅲ diesel specifications can be produced by blends of AGO，LCO as well as blends of AGO，CGO；clean diesel meeting national Ⅳ diesel specifications can be produced by AGO. Meanwhile，the longer stable running of this unit proves that SRH diesel products liquid recycling hydrogenation technology and key devices are mature and reliable.
