Abstract

Olefins are oligomerized by bringing at least one C2 to C8-olefin into contact with a nickel-containing heterogeneous catalyst. The catalyst is conditioned before contact with the olefin by passing an inert gas flow over the same, until the inert gas flow has a water content of less than 1000 ppm. Selectivity for the production of higher oligomers, in particular trimers relative to the formation of dimers is increased by the pretreatment.
