摘要

A catalyst contains an NES type zeolite(s), at least part in acid form and containing silicon and an element T from aluminum, iron, gallium and/or boron, and a group VIIB or VIB metal and iridium. A catalyst comprises a binder, an NES type zeolite(s), at least part in acid form and containing an element T from silicon and aluminum, iron, gallium and/or boron, and a group VIIB or VIB metal and iridium. An Independent claim is included for the preparation of the above catalyst by removing aluminum from an NES zeolite by direct acid attack.
