Barnett, K W; Brown, M J

A method is described of oligomerizing an olefin comprising: contacting the olefin with a nickel-omega zeolite catalyst at a pressure, temperature and for a time effective to cause oligomerization of the olefin; the catalyst comprising a nickelocene compound reduced onto an omega zeolite support in the presence an effective amount of a promoter; wherein the nickelocene compound is selected from the group consisting of (R/sub a/-eta/sup 5/ cyclopentadienyl) (cyclopentadienyl) Ni and bis(R/sub a/-eta/sup 5/ cyclopentadienyl) Ni wherein R represents C/sub 1/-C/sub 10/ alkyl and ''a'' represents 0-5; and wherein the promoter is selected from the group consisting of an oxide of copper, nickel, iron and mixtures thereof.
