ABSTRACT:
A method of pre-conditioning the walls of an olefin dimerization reactor and starting a dimerization process comprises sequential steps of introducing a first soluble homogeneous catalyst component comprising, e.g. a complex of a divalent metal selected from the group consisting of nickel, cobalt and iron, and a second soluble homogeneous catalyst component comprising, e.g. an organoaluminum compound, at rates such that the molar catalyst feed ratio of said aluminum to said divalent metal is maintained at a first value during the pre-conditioning and startup period and at a second, higher, value during the operating period.
