VERFAHREN ZUR HERSTELLUNG VON AROMATISCHEN VERBINDUNGEN AUS ALIPHATISCHEN KOHLENWASSERSTOFFEN

摘要

A dehydrocyclo-oligomerization process is provided for converting aliphatic hydrocarbons to aromatics by contacting the feedstock under conversion conditions which a zeolite bound zeolite catalyst. The zeolite bound zeolite catalyst comprises first zeolite crystals which are bound together by second zeolite crystals. If the zeolite bound zeolite catalyst is selectivated, the process can produce greater than equilibrium amounts of paraxylene.
