Feeds containing triglycerides are processed to produce an olefinic diesel fuel product. The olefinic diesel can optionally be oligomerized to form a lubricant base oil product. The olefinic diesel is generated by deoxygenating the triglyceride-containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal or a Group VIII metal and optionally a physical promoter metal.

Production of olefinic diesel and corresponding oligomers

A process for converting light paraffins (especially C-C) to middle distillate and higher boiling range liquid hydrocarbons by (1) oxygen or air oxidation of iso-paraffins to alkyl hydroperoxides; (2) conversion of alkyl hydroperoxides to dialkyl peroxides; (3) radical coupling of paraffins using the dialkyl peroxides as radical initiators forming heavier hydrocarbon products; and (4) fractionation of the heavy hydrocarbon products. The net reaction is catalytically converting light paraffins to heavier hydrocarbons using oxygen or air to effect the conversion.

Upgrading paraffins to distillates and lubricant basestocks

Provided are processes for making hydrocarbons from renewable feed sources. In an embodiment, there is provided a method for co-producing lube basestock and transportation fuel from a feedstock of biological origin, the method including: a) converting a feedstock of biological origin to a ketone or a dimer acid in the presence of a first catalyst; and b) hydrogenating the ketone or the dimer acid to produce a hydrocarbon in the presence of a second catalyst comprising a hydrogenation catalyst and a hydrothermally stable binder.

Process for making lube base stocks from renewable feeds

Provided are processes for making saturated hydrocarbons from renewable feed sources. In an embodiment, a process for producing a lube basestock and/or a diesel fuel from a feedstock of biological origin includes: contacting the feedstock in a single reactor in the presence of hydrogen with catalyst components including a first catalyst and a second catalyst, wherein the first catalyst comprises an acidic material, a basic material, or a combination of both, and wherein the second catalyst is a hydrogenation catalyst including a hydrothermally stable binder.

Process for making saturated hydrocarbons from renewable feeds

Feeds containing triglycerides are processed to produce an olefinic diesel fuel product and propylene. The olefinic diesel can optionally be oligomerized to form a lubricant base oil product. The olefinic diesel and propylene are generated by deoxygenating the triglyceride-containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal or a Group VIII metal and optionally a physical promoter metal.

Production of olefinic diesel, lubricants, and propylene

A process for making a substantially saturated dendritic hydrocarbon polymer. The process has the following steps: (a) polymerizing an amount of a first alkadiene monomer under anionic conditions in the presence of a first organic monolithium initiator to produce a linear polyalkadiene having a lithiated chain end; (b) reacting the linear polyalkadiene with an amount of a second organic monolithium initiator in the presence of tetramethylethylene diamine to form a multilithiated polyalkadiene; (c) reacting the multilithiated polyalkadiene with an amount of a second alkadiene monomer to form a branched polyalkadiene; (d) repeating steps (b) and (c) with the branched polyalkadiene one or more times to prepare a dendritic polyalkadiene; and (e) hydrogenating the dendritic polyalkadiene to form the substantially saturated dendritic hydrocarbon polymer.

A poly(alpha-olefin/alkylene glycol) copolymer of the following formula: wherein R, R, Ra, and Rb are, independently, any of H, a Cto Cnormal or branched alkyl radical, or a Cto Caromatic radical or aromatic-containing alkyl radicals; wherein n and m, are, independently, integers from 1 to 1000; and wherein x is an integer from 0 to 10. There is also a process for making the copolymer. There is also a lubricant formulation having the copolymer.
