Abstract

To provide methods of producing branched aliphatic alkenes via dimerization reactions and catalysts used therein.SOLUTION: A method of producing a branched aliphatic alkene comprises a step for reacting a feed stream comprising aliphatic alpha olefins with a supported alkali metal or alkali metal composite catalyst to produce the branched aliphatic alkene. The support comprises a mixed metal oxide comprising a Column 1 metal and at least one of a Column 3 metal, a Column 4 metal, or a lanthanide. The catalyst has less than 50 wt.% of a metal carbonate.SELECTED DRAWING: Figure 1A
