Embodiment Construction

[0245] Ordinary catalysis was performed in a 300 mL volume High Pressure Engineered Reactor equipped with a stainless steel vessel with a removable thermofluid jacket or in a 1.2 L Premex autoclave with a stainless steel vessel with an integral thermofluid jacket. Both reactors were equipped with mechanical gas entrainment stirring and internal cooling coils. Ethylene (grade 4.5) was supplied by Linde and passed through a scrubber before use; the flow of ethylene was measured and recorded using a Siemens Sitrans FC Massflo system (Mass 6000-Mass 2100). GC analysis was performed using an Agilent Technologies 6850Network GC system equipped with a PONA column (50 m x 0.20 mm x 0.50 μm) and using hydrogen as a carrier gas. All catalytic tests were run until ethylene uptake ceased either because the catalyst was deactivated or because the autoclave had filled up.

Abstract

This invention relates to the oligomerisation of olefinic compounds in the presence of an activated oligomerisation catalyst. The invention also extends to a particular manner for providing an activated oligomerisation catalyst. According to the the present invention, there is provided a process for producing an oligomeric product by the oligomerisation of at least one olefinic compound, the process including (a) providing an activated oligomerisation catalyst by combining, in any order, and (b) contacting the at least one olefinic compound with the activated oligomerisation catalyst to produce an oligomeric product.

Description

technical field [0001] The present invention relates to the oligomerization of olefinic compounds in the presence of an activated oligomerization catalyst. The present invention also relates to specific ways of providing activated oligomerization catalysts. Background technique [0002] A large number of different oligomerization techniques are known to produce alpha-olefins. Some of these processes have been summarized in WO 04 / 056479A1, including the Shell higher olefins process and Ziegler-type techniques. Said document also discloses that the prior art (such as WO 03 / 053891 and WO 02 / 04119) teaches that chromium-based catalysts containing heteroaromatic ligands selectively catalyze the trimerization of ethylene to 1-hexene, said heteroaromatic Ligands have both phosphorus and nitrogen heteroatoms. [0003] Additionally, in various patent applications such as WO 03 / 053890A1, WO 03 / 053891, WO 04 / 056479A1, WO 04 / 056477A1, WO 04 / 056480A1, WO 04 / 056478A1, WO 05 / 123884A2, W...
