Abstract
Oligomerization catalyst and method for oligomerization using the catalyst. The catalyst comprises a single Zn(II) or Ga(III) metal ion center directly bonded to a support through a shared oxygen atom, the catalyst having at least one M-O bond which forms an active site for oligomerization. The method includes reacting one or more C2 to C12 olefins with the oligomerization catalyst at a temperature of about 200° C. or higher to provide an oligomer product comprising C4 to C26 olefins.
