The present invention relates to the field of oligomerization of olefins to produce linear α-olefins, in particular hexene-1, using catalyst systems. The catalyst system comprises a chromium source compound, a nitrogen-containing ligand, an alkylaluminum, and a zinc compound, wherein the catalyst system 1) heats a portion of the alkylaluminum or a mixture of the alkylaluminum and the zinc compound during its preparation and By performing SHF irradiation (microwave irradiation) on the alkyl aluminum or the mixture of the alkyl aluminum and the zinc compound, or 2) heating the alkyl aluminum or the mixture of the alkyl aluminum and the zinc compound, and then setting the prepared catalyst system for a specific time. It is activated by holding it during (aging). |
