Metal-containing zeolite catalyst, preparation thereof and use for hydrocarbon conversion

摘要

There is provided a zeolite bound zeolite catalyst which does not contain significant amounts of non-zeolitic binder and a process for converting hydrocarbons utilizing the zeolite bound zeolite catalyst. The catalyst comprises first zeolite, crystals, a binder comprising second zeolite crystals and a hydrogenation/dehydrogenation metal. The zeolite bound zeolite catalyst is prepared by converting the silica binder of a silica bound aggregate containing the first crystals of said first zeolite and at least a portion of the hydrogenation/dehydrogenation metal to said second zeolite. Conversion processes such as naphtha reforming xylene isomerization/ethylbenzene conversion, the zeolite bound zeolite catalyst has excellent performance when used in hydrocarbon conversion processes such as naphtha reforming and xylenes isomerization/ethylbenzene conversion.
