<p>A denitrification method is disclosed for removing nitrogen compounds from a hydrocarbon feed in which the feed is contacted with an adsorbent including an organic heterocyclic salt deposited on a porous support. Additionally, a method for hydrotreating a hydrocarbon feed which includes a hydroprocessing step is disclosed, wherein prior to hydroprocessing, the feed is contacted with an adsorbent including an organic heterocyclic salt deposited on a support. Additionally, a method for producing a lube oil which includes isomerization dewaxing of a base oil fraction is disclosed, wherein prior to the isomerization dewaxing step, the base oil fraction is contacted with an adsorbent including an organic heterocyclic salt deposited on a support.</p> |
