Alkylated Naphthalene Compositions Obtained Through Blending Or Processing Of Monoalkylated And Dialkylated Naphthalene Fractions
Alkylated naphthalene compositions are usually formed by reacting naphthalene with an electrophilic agent under acid-catalyzed conditions to afford a mixture of monoalkylated naphthalenes, dialkylated naphthalenes, and sometimes polyalkylated naphthalenes. Reaction conditions are usually chosen to change the product distribution for purposes of modifying lubricant properties such as viscosity or volatility. Rarely does the product distribution exceed 90 wt. % monoalkylated naphthalenes. Viscosity and volatility may alternately be modified by obtaining a first fraction enriched in monoalkylated naphthalenes and a second fraction enriched in dialkylated naphthalenes and combining the first fraction and the second fraction in a specified ratio to produce a modified alkylated naphthalene composition having a targeted value of one of the viscosity or the volatility. The first fraction and the second fraction may be obtained by fractional distillation of a first alkylated naphthalene composition to afford an overhead fraction and a bottoms fraction.

A hydroprocessor feed that includes the gas oil feed if R(go)≤R(ref) or the heat-treated gas oil feed can be fed to a hydroprocessor. The hydroprocessor feed can be hydroprocessed in the hydroprocessor to produce a hydroprocessor effluent that can include a hydroprocessed gas oil.

Membrane-Based Separation Processes Enhanced with an Absorption Device
A salt ion membrane may be paired with an absorption device to provide advantaged separation processes comprising: introducing a first aqueous salt stream and a mixed feed stream comprising at least one olefin and at least one paraffin to a salt ion membrane under conditions effective to form at least two phases; obtaining an olefin-rich permeate stream and an olefin-lean retentate stream from the salt ion membrane, in which the olefin-rich permeate stream and/or the olefin-lean retentate stream further comprises a salt ion membrane aqueous salt phase; introducing at least a portion of the olefin-lean retentate stream and a second aqueous salt stream to an absorption device under conditions effective to promote olefin extraction; obtaining an olefin-rich aqueous salt stream from the absorption device; and providing at least a portion of the olefin-rich aqueous salt stream as at least a portion of the first aqueous salt stream.

Processes for converting an alkane to an alkene. In some embodiments, the process can include contacting a hydrocarbon-containing feed with a first catalyst that can include Pt or a second catalyst that can include Cr within a conversion zone to effect dehydrogenation of at least a portion of the hydrocarbon-containing feed to produce an effluent that can include one or more dehydrogenated hydrocarbons and molecular hydrogen. The process can also include contacting the effluent with a solid oxygen carrier disposed within the conversion zone to effect combustion of at least a portion of the molecular hydrogen to produce a conversion product that can include the one or more dehydrogenated hydrocarbons and water. In some embodiments, contacting the feed with the first or second catalyst can occur in a first conversion zone and contacting the effluent with the solid oxygen carrier can occur in a second conversion zone.
Catalyst compositions and processes for making and using same. The catalyst composition can include catalyst particles. The catalyst particles can include 0.001 wt % to 6 wt % of Pt and up to 10 wt % of a promoter that can include Sn, Cu, Au, Ag, Ga, or a combination thereof, or a mixture thereof disposed on a support. The support can include at least 0.5 wt % of a Group 2 element. All weight percent values are based on the weight of the support. The catalyst particles can have a median particle size in a range from 10 μm to 500 pm. The catalyst particles can have an apparent loose bulk density in a range from 0.3 g/cm3 to 2 g/cm3, as measured according to ASTM D7481-18 modified with a 10, 25, or 50 mL graduated cylinder instead of a 100 or 250 mL graduated cylinder.
