    Abstract: The present invention relates to a process for the preparation of linear low molecular weight alpha-olefins having 4 to 24 carbon atoms, comprising oligomerizing ethylene in an inert solvent in the presence of a catalyst system comprising: (i) zirconium car-boxylate of the formula (R 1 COO) m ZrCl 4-m , wherein R 1 is saturated or unsaturated ali-phatic C 1 -C 10 hydrocarbon or aromatic C 6 -C 14 hydrocarbon and m fulfills 1 ≤ m ≤ 4, (ii) at least one aluminum compound selected from organoaluminum compounds of the formula R 2 n A1X 3-n , wherein R2 is C 1 -C 20 alkyl, X is chlorine, bromine or iodine, and n fulfills 1 ≤ n ≤ 2, and/or aluminoxanes, and (iii) at least two different additives selected from the group consisting of hydrogen, esters, ketones, ethers, amines, anhydrides, phosphines and sulfur compounds; as well as to a catalyst used therein.
