摘要: A method is disclosed for removing impurities such as nitrogen and/or sulfur compounds from a hydrocarbon feed, in which the feed contacted with an adsorbent including nitrogen-containing organic heterocyclic salt deposited on porous support, e.g., supported ionic liquid. Additionally, hydrotreating includes hydroprocessing step disclosed, wherein prior to hydroprocessing, producing lube oil isomerization dewaxing of base fraction step, In one embodiment, regenerated restore its treatment capacity.
