Abstract
The present invention discloses processes for oligomerizing an olefin feedstock containing Cto Calpha olefins using a catalyst system containing a metallocene compound, an organoaluminum compound, and a suspension of a chemically-treated solid oxide. The liquid medium for the suspension of the chemically-treated solid oxide can be an alpha-olefin oligomer product formed by the oligomerization process.
