Title:
脱アルミニウムゼオライトNU―86および炭化水素の転換におけるその使用法
Document Type and Number:
Japanese Patent JP4344853
Kind Code:
B2
Abstract:
A process for the catalytic conversion of hydrocarbons, in particular for the oligomerization of olefins wherein the catalyst comprises a zeolite which is at least partially in its acid form. The zeolite is a NU-86 zeolite comprising silicon and at least one element T selected from the group formed by aluminum, iron, gallium and boron, preferably aluminum, 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.
