ABSTRACT:
A catalytic composition for the production of light alpha olefins by ethylene oligomerisation is produced by mixing a zirconium compound with an organic compound selected from the group formed by acetals and ketals, with an aluminium hydrocarbyl compound selected from the group formed by chlorine-containing or bromine-containing aluminium hydrocarbyl compounds and with an aluminium hydrocarbyl compound selected from tris-(hydrocarbyl)-aluminium compounds. Addition of a tris-(hydrocarbyl)-aluminium compound greatly increases the activity. A process for producing light alpha olefins by ethylene oligomerisation is also claimed.
