Abstract
Aspects of the present disclosure relate to a process for producing synthetic hydrocarbon base oils having advantageous properties for formulation of engine oils, and the base oils obtained by such processes, involving the production of branched alkenes from the oligomerization of C14-C18 olefins. According to one embodiment, the base oils are obtained by first forming a mixture of two or more olefins ranging from C14-C18, where one of the olefins is an alpha olefin and the other has an average double bond position between 1.5-5.0, and oligomerizing this mixture in the presence of a catalyst to form one or more branched alkenes, hydrogenating the branched alkenes, and fractionating to form base oils. According to one aspect, advantageous properties can be obtained by controlling one or more of the degree of branching, branch length, branching positions, selection of the C14-C18 olefins, and catalytic isomerization, during or after the oligomerization process.
