Patent

CA 2254893

A dehydrocyclo-oligomerization process is provided for converting aliphatic hydrocarbons to aromatics by contacting the feedstock under conversion conditions with 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.

Le procédé de déhydrocyclo-oligomérisation permet de convertir des hydrocarbures aliphatiques en aromatiques en mettant en contact le matériau d'alimentation, dans des conditions de conversion, avec un catalyseur zéolite lié à une zéolite. Le catalyseur de zéolite lié à une zéolite comprend des cristaux d'une première zéolite qui sont liés ensemble par des cristaux d'une seconde zéolite. Si le catalyseur de zéolite lié à une zéolite est "sélectivé", le procédé peut produire des quantités de paraxylène supérieures aux quantités d'équilibre.
