Title
(EN) MEL-TYPE ZEOLITE FOR CONVERTING AROMATIC HYDROCARBONS, PROCESS FOR MAKING AND CATALYTIC COMPOSITION COMPRISING SAID ZEOLITE
(FR) ZÉOLITE DE TYPE MEL POUR LA CONVERSION D'HYDROCARBURES AROMATIQUES, PROCÉDÉ DE FABRICATION ET COMPOSITION CATALYTIQUE COMPRENANT LADITE ZÉOLITE
Abstract
(EN)
Novel MEL framework type zeolites can be made to have small crystallite sizes and desirable silica/SiCb molar ratios. Catalyst compositions comprising such MEL framework type zeolites can be particularly advantageous in isomerization C8 aromatic mixtures. An isomerization process for converting C8 aromatic hydrocarbons can advantageously utilize a catalyst composition comprising a MEL framework type zeolite.
(FR)
De nouvelles zéolites de type à structure MEL peuvent être fabriquées pour avoir de petites tailles de cristallites et des rapports molaires de silice/SiCb souhaitables. Des compositions de catalyseur comprenant de telles zéolites de type à structure MEL peuvent être particulièrement avantageuses dans l'isomérisation de mélanges aromatiques en C8. Un procédé d'isomérisation pour convertir des hydrocarbures aromatiques en C8 peut avantageusement utiliser une composition de catalyseur comprenant une zéolite de type à structure MEL.
