Title: Dealuminated NU-86 zeolite and its use for the conversion of hydrocarbons

Abstract: The invention concerns a NU-86 zeolite comprising silicon and at least one element T selected from the group formed by aluminium, iron, gallium and boron, preferably aluminium, characterized in that element T has been extracted from the framework, and in that it has a global Si/T atomic ratio of more than about 20. Element T is extracted from the zeolitic framework (or network) by means of at least one heat treatment, optionally carried out in the presence of steam, followed by at least one acid attack using at least one solution of a mineral or organic acid, or by direct acid attack. The invention also concerns a catalyst comprising the zeolite which is at least partially in its acid form, and the use of the catalyst for the conversion of hydrocarbons, in particular for the oligomerization of olefins.
