Title:

METAL ZEOLITE OLIGOMERISATION CATALYSTS, THEIR PREPARATION AND USE

Document Type and Number:

WIPO Patent Application WO/2016/123640

Kind Code:

A3

Abstract:

The invention provides a method of manufacture of a catalyst, the catalyst as such and its use in olefin oligomerisationand. The method for making an oligomerisation catalyst includes the steps of mixing alumina, silica, metal oxide, a template source; and effecting the deactivation of the Bronsted sites by masking them with metal ions, preferably either (i) during synthesis by directly adding the metal as ion in a one-pot or direct synthesis, or (ii) after intermidiate conversion to the H+-form by in turn either (ii-a) impregnating the latter with a metal salt, or (ii-b) dry-mixing a metal salt with it.
