FIELD: petroleum processing.
SUBSTANCE: prior to be subjected to hydrotreatment, fuel is brought into contact with selective adsorbent to remove desulfurization inhibitors, after which fuel with reduced level of desulfurization inhibitors is separated from adsorbent without significant loss and undergoes hydrotreatment to produce pure diesel fuel containing below 500 ppm total sulfur, whereas adsorbent is regenerated and recycled back into adsorption zone.
EFFECT: improved quality of desired product.
