Abstract (en)

[origin: FR2755958A1] The invention concerns a NU-86 zeolite, containing silicon, and at least one element T selected from the group formed by aluminium, iron, gallium and boron, preferably aluminium, characterised in that the element T has been extracted from the structure and in that it has a global atomic Si/T greater than about 20. The extraction of the element T from the zeolite structure (or network) is effected by at least a thermal treatment. optionally carried out in the presence of water vapour, followed by at least an acid attack, by at least a mineral or organic acid solution, or by a direct acid attack. The invention also concerns a catalyst comprising said zeolite at least partly in acid form and the use of said catalyst in hydrocarbon conversion, in particular in the oligomerization of olefins.
