Answer: (1) Atmospheric and vacuum distillation. (2) Catalytic cracking. (3) Coking. (4) Refining in the tank farm.
atmospheric and vacuum distillation； Catalytic cracking ； Coking ； Re-refining in the tank farm.
Among them, straight-run diesel and coker (catalytic) diesel are the most common. These diesel fractions all contain various levels of contaminating impurities and different types of non-ideal components, and their presence has a significant impact on the performance of diesel. The purpose of diesel hydroprocessing is to produce high-quality diesel or components that can be used to formulate high-quality diesel.

Any diesel is suitable; currently, diesel hydrotreatment mainly involves hydrodesulfurization and hydroisomerization. For desulfurization, the feedstock is usually regular diesel or coker diesel, with some catalytic diesel being added depending on the requirements of the final product. For hydroisomerization, catalytic diesel is generally used as the feedstock.
