OLIGOMERISATION IN THE PRESENCE OF BOTH A TETRAMERISATION CATALYST AND A FURTHER OLIGOMERISATION CATALYST

摘要

This invention relates to a process for the oligomerisation of at least one olefinic compound in the form of an olefin or a compound including an olefinic moiety by contacting the at least one olefinic compound with at least two different catalysts, namely a tetramerisation catalyst and a further oligomerisation catalyst. The tetramerisation catalyst comprises a combination of a source of a transition metal; and a ligating compound of the formula (R<1>)m X<1> (Y) X<2> (R<2>)n. The invention also relates to an oligomerisation catalyst comprising the combination of (i) source of transition metal for both a tetramerisation catalyst and a trimerisation catalyst; (ii) a ligating compound for a tetramerisation catalyst; (iii) a different ligating compound for a trimerisation catalyst; and (iv) optionally an activator.
