其目的是在氢压和催化剂作用下使油品中的硫、氧、氮等有害 杂质转变为相应的硫化氢、水、氨而除去，并使烯烃和二烯烃 加氢饱和、芳烃部分加氢饱和，部分金属及沥青杂质得以脱除， 以达到改善油品的气味、颜色和安定性，防止腐蚀，进一步提 高产品质量，满足油品的使用要求。
Hydro refining can generally be divided into two categories according to its refining purpose: one is to directly produce clean fuel oil; the other is to provide high-quality raw materials for other processes or devices.

加氢精制各种油品在氢压下进行改质的总称
The Purpose of hydro refining
加氢精制的目的
——to transform sulfur, oxygen, nitrogen and other harmful impurities in the oil products into homologous hydrogen sulfide, water, ammonia under the role of hydrogen pressure and catalyst, and then get them removed. Besides, it also aims to achieve the hydrogenation and saturation of alkene and alkadiene as well as partial hydrogenation and saturation of aromatic hydrocarbon, and eliminate partial medal and asphalt impurities in order to improve the smell, color and stability of oil products, prevent corrosion, further improve product quality and meet the request for utilization.
