Abstract
The present disclosure relates to a catalyst composition for the oligomerization of ethylene comprising a zirconium-containing catalyst and an organoaluminum-containing co-catalyst. The disclosure also relates to a process for oligomerization of ethylene in the presence of the catalyst composition according to the disclosure. The disclosed process results in C4-C20 linear alpha olefins having improved linearity.
