摘　　要：综述了蜡油、柴油、航煤等加氢原料的液相处理技术。加氢技术从固定床加氢发展为液相加氢的技术,和柴油液相加氢的SRH技术和SLHT技术、煤油液相加氢的CLTH技术和C-NUM技术。对比了上行式工艺技术和下行式工艺中催化剂裸露情况的不同,分析了循环油对液相加氢工艺能耗的影响。结果表明,液相加氢技术的主要优势是低能耗,但是不适合加工焦化蜡油,对于氢耗量较高的催化柴油等原料也有待深入研究。采用强化混氢技术可以降低传质阻力,将成为国内外液相加氢技术发展的方向。The liquid phase treatment techniques for hydrogenation feedstocks such as wax oil,diesel oil,aviation kerosene,etc.are reviewed.The earliest hydrogenation technology developed from fixed bed hydrogenation to liquid phase hydrogenation,including SRH technology and SLHT technology for diesel liquid phase hydrogenation,CLTH technology and C-NUM technology for kerosene liquid phase hydrogenation.The differences in catalyst exposure between the upstream process and the downstream process were compared,and the impact of circulating oil on the energy consumption of the liquid phase hydrogenation process was analyzed.The results show that the main advantage of liquid phase hydrogenation technology is low energy consumption,but it is not suitable for processing coking gas oil.For feedstocks such as catalytic diesel with high hydrogen consumption,further research is also needed.Using enhanced hydrogen mixing technology can reduce mass transfer resistance,which will become the development direction of liquid phase hydrogenation technology at home and abroad.
