Abstract
Provided is a process for preparing oligomers from an alkane. The process comprises (a) contacting an alkane under dehydrogenation conditions in the presence of a dehydrogenation catalyst such as an iridium catalyst complex comprising iridium complexed with a benzimidiazolyl-containing ligand to form olefins, and (b) contacting the olefins prepared in step (a) under oligomerization conditions with an oligomerization catalyst such as a nickel, platinum or palladium metal catalyst complex comprising the metal complexed with a nitrogen containing bi- or tridentate ligand to prepare oligomers of the olefins, and hydrogenating the olefin oligomers. In one embodiment, the ligands of the catalyst complexes in step (a) and step (b) can be the same.
