Method of Preparation of Catalyst System for Olefin Oligomerization |
| abstract |
FIELD OF THE INVENTION The present invention relates to the field of olefin oligomerization for the production of alpha olefins, in particular hexene-1 used in the production of linear low and high density polyethylenes, polyhexenes and the like. A) premixing at least one source of chromium and at least one nitrogen-containing ligand in at least one hydrocarbon solvent to form a premixed composition; and B) mixing the premixed composition with at least one activator, wherein the mixing of step B) is provided in a laminar flow condition or in a laminar flow condition. and turbulent flow conditions. Various embodiments of the method are disclosed. The catalyst system may be previously subjected to microwave irradiation (UHF irradiation) in a hydrocarbon solvent. The present invention provides for increased stability of the catalyst system and reduced consumption standards of the initial components of the catalyst system. |
