Abstract
The invention concerns an improved process for the conversion of ethylene into light alpha olefins wherein the ethylene is brought into contact with a catalyst obtained by mixing a compound of zirconium with an organic compound selected from the class of acetals and ketals, esters, ketones, ethers, amines, nitrites, anhydrides, chlorides of acids, amides, aldehydes, thioethers, sulphides and disulphides, thiophenes, thioureas and phosphines, and with a chloro or bromo compound of aluminium hydrocarbyl, in the presence of an additive formed by at least one quaternary ammonium salt.
