Abstract: The present invention is directed to the method drilling a borehole with monoester-based drilling fluid compositions. In some embodiments, the methods for making such monoester-based lubricants utilize a biomass precursor and/or low value Fischer-Tropsch (FT) olefins and/or alcohols so as to produce high value monoester-based drilling fluids. In some embodiments, such monoester-based drilling fluids are derived from FT olefins and fatty acids. The fatty acids can be from a bio-based source (i.e., biomass, renewable source) or can be derived from FT alcohols via oxidation.

Abstract: This invention discloses a process for making high viscosity index lubricating base oils having a viscosity index of at least 110 by co-feeding a ketone or a beta-keto-ester feedstock with a lubricant oil feedstock directly to a hydrocracking unit to produce a hydrocracked stream. Then at least a portion of the hydrocracked stream is treated under hydroisomerization conditions to produce a high viscosity index lubricating base oil. The process may involve bypassing a hydrotreating or hydrofinishing step, which may result in improved efficiency and economics in producing high viscosity index lubricating base oils.

Abstract: Disclosed herein are monoester-based lubricant compositions and methods of making these monoester-based lubricant compositions. The monoester lubricant compositions comprise an isomeric mixture of at least one monoester species having a carbon number ranging from C8 to C40. In some embodiments, the methods for making the monoester-based lubricants utilize a biomass precursor and/or low value Fischer-Tropsch (FT) olefins and/or alcohols to produce high value monoester-based lubricants. In some embodiments, the monoester-based lubricants are derived from FT olefins and fatty acids. The fatty acids can be from a bio-based source (i.e., biomass, renewable source) or can be derived from FT alcohols via oxidation.

Abstract: A process for removing heavy polycyclic aromatic contaminants from a hydrocarbon stream using a quinolinium ionic liquid is described. The process includes contacting the hydrocarbon stream comprising the contaminant with a hydrocarbon-immiscible quinolinium ionic liquid to produce a mixture comprising the hydrocarbon and a hydrocarbon-immiscible quinolinium ionic liquid comprising at least a portion of the removed contaminant; and separating the mixture to produce a hydrocarbon effluent having a reduced level of the contaminant and a hydrocarbon-immiscible quinolinium ionic liquid effluent comprising the hydrocarbon-immiscible quinolinium ionic liquid comprising at least the portion of the removed contaminant.

Abstract: A process is provided for removing a heavy polynuclear aromatic (HPNA) compound from a hydrocarbon oil. The process includes contacting the hydrocarbon oil containing the HPNA compound with a lean hydrocarbon-immiscible liquid stream to produce a mixture comprising the hydrocarbon oil and a rich hydrocarbon-immiscible liquid containing the HPNA compound; and separating the mixture to produce a hydrocarbon oil effluent having a reduced level of the HPNA compound and a hydrocarbon-immiscible liquid effluent containing the HPNA compound. The hydrocarbon-immiscible liquid can be a halometallate ionic liquid, a liquid coordination complex, or a combination thereof.
