Abstract: Adsorbents for aromatic adsorption are used to improve one or more properties of base stocks derived from deasphalted oil fractions. The adsorbents can allow for removal of polynuclear aromatics from an intermediate effluent or final effluent during base stock production. Removal of polynuclear aromatics can be beneficial for improving the color of heavy neutral base stocks and/or reducing the turbidity of bright stocks.
