Abstract: In a process for the catalytic alkylation of an olefin with an isoparaffin, an olefin-containing feed is contacted with an isoparaffin-containing feed under alkylation conditions in the presence of a solid acid catalyst comprising a crystalline microporous material of the MWW framework types, wherein the olefin-containing feed consists essentially of pentenes.

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.
