HEAVY AROMATICS PROCESSING
A heavy aromatics feed is converted to lighter aromatics products, such as benzene, by contacting a C9+ aromatics fraction and toluene over a first catalyst comprising a zeolite having a constraint index ranging from 0.5 to 3 and a hydrogenation component, and a second catalyst composition comprisin...

| description | A heavy aromatics feed is converted to lighter aromatics products, such as benzene, by contacting a C9+ aromatics fraction and toluene over a first catalyst comprising a zeolite having a constraint index ranging from 0.5 to 3 and a hydrogenation component, and a second catalyst composition comprising an intermediate pore size zeolite having a constraint index ranging from 3 to 12 and a silica to alumina ratio of at least 5, whereby the amount of coboilers is reduced or eliminated.
Une charge d'aromatiques lourds est transformée en produits aromatiques plus légers, tels que du benzène, par mise en contact d'une fraction d'aromatiques C9+ et de toluène sur un premier catalyseur qui comporte un zéolite présentant un indice de contrainte compris entre 0,5 et 3 et un composant d'hydrogénation; et sur une deuxième composition de catalyseur comportant un zéolite à dimensions moyennes de pores, qui présente un indice de contrainte compris entre 3 et 12 et un rapport silice/alumine d'au moins 5, la quantité de sous-produits de cuisson étant ainsi réduite ou éliminée. |
