METHOD OF PRODUCING OLEFIN OLIGOMERISATION CATALYST SYSTEM AND OLEFIN OLIGOMERISATION METHOD Russian patent published in 2011 - IPC B01J37/34 B01J37/04 B01J31/18 B01J23/26 C07C2/30

Abstract RU 2412002 C1

FIELD: chemistry.

SUBSTANCE: invention relates to production of chromium-containing catalyst systems and use thereof in synthesis of hydrocarbons, specifically an olefin oligomerisation method. Described is a method of producing a catalyst system for trimerisation or oligomerisation of olefins, involving a step for mixing a chromium source, a nitrogen-containing ligand and alkyl aluminium in a common solvent in which alkyl aluminium is exposed to microwave radiation when producing the catalyst system. The invention also describes a method for trimerisation or oligomerisation of an olefin compound containing 2-30 carbon atoms per molecule and at least one terminal olefin double bond, involving a trimerisation or oligomerisation step in the presence of the catalyst system obtained using the method described above.

EFFECT: high selectivity of the oliefin oligomerisation and trimerisation reactions, high activity of the catalyst system.
