Abstract: A process for converting light paraffins to heavier paraffinic hydrocarbon fluids is disclosed. The process involves: (1) oxidation of iso-paraffins to alkyl hydroperoxides and alcohols; (2) conversion of the alkyl hydroperoxides and alcohols to dialkyl peroxides; and (3) radical-initiated coupling of paraffins and/or iso-paraffins using the dialkyl peroxides as radical initiators, thereby forming heavier hydrocarbon products. Fractionation of the heavy hydrocarbon products can then be used to isolate fractions for use as hydrocarbon fluids.

Abstract: 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.
