摘　　要：针对不同柴油馏分及其加氢精制产物的窄馏分考察油品烃类组成和颜色的关系,并在中型试验装置上考察了工艺条件对加氢精制柴油显色物质的影响。结果表明:柴油馏分中的显色物质主要集中于较重的馏分中,造成加氢精制柴油颜色变深的物质主要是芘和荧蒽类四环芳烃;通过提高氢分压或提高氢油比可以打破这些多环芳烃显色物质的加氢平衡,从而得到颜色浅、色号小的产物。The properties of diesels from different sources and the hydrogenated products were analyzed in detail,and the relationship between hydrocarbon composition and color of hydrotreated diesel with narrow distillation range was investigated.The influence of process conditions on the color materials of hydrotreated diesel was researched in a medium scale test unit.The results show that the color materials in the diesel fractions are mainly concentrated in the heavier fractions,and the main color materials in hydrotreated diesel are pyrene and fluoranthrene.By increasing hydrogen partial pressure or hydrogen-oil ratio,the hydrogenation equilibrium of PAHs can be broken,resulting in the product of light color.
