[0002] Hydrogen treatment is an important refining method for diesel products. Specifically, under the presence of hydrogen pressure and catalyst, harmful impurities such as sulfur, oxygen, nitrogen, etc. in the oil are converted into corresponding hydrogen sulfide, water, and ammonia and removed to improve the quality of the oil.
