Abstract: Methods and apparatuses for reducing an aromatic concentration in a hydrocarbon stream are provided. In an embodiment, a method for reducing an aromatic concentration in a hydrocarbon stream includes saturating aromatics in the hydrocarbon stream to form a low aromatic hydrocarbon stream comprising no more than about 2 weight percent (wt %) aromatics. Further, the method includes passing the low aromatic hydrocarbon stream through an adsorption zone to remove aromatics therefrom to form an aromatic-depleted product stream comprising less than about 10 weight parts per million (wppm) aromatics.
