Title
(EN) ISOMERIZATION OF PARAFFINS
(FR) ISOMERISATION DE PARAFFINES
Abstract
(EN)
This invention relates to a process for isomerizing paraffins comprising the step of contacting a feed containing paraffins with a catalyst comprising a synthetic porous crystalline material, designated MCM-68, which exhibits a distinctive X-ray diffraction pattern and has a unique crystal structure which contains at least one channel system, in which each channel is defined by a 12-membered ring of tetrahedrally coordinated atoms, and at least two further, independent channel systems, in each of which each channel is defined by a 10-membered ring of tetrahedrally coordinated atoms, wherein the number of unique 10-membered ring channels is twice the number of 12-membered ring channels.
(FR)
L'invention se rapporte à un procédé d'isomérisation de paraffines, qui consiste à placer une charge d'alimentation contenant des paraffines au contact d'un catalyseur contenant une matière cristalline poreuse synthétique, appelée MCM-68. Cette matière cristalline poreuse synthétique présente un diagramme de diffraction des rayons X distinctif, ainsi qu'une structure cristalline simple comprenant au moins un système à canaux dans lequel chaque canal est délimité par un noyau à 12 chaînons d'atomes à coordination tétraédrique, et au moins deux autres systèmes à canaux indépendants dont chaque canal est délimité par un noyau à 10 chaînons d'atomes à coordination tétraédrique, le nombre de canaux simples à noyau à 10 chaînons étant le double du nombre de canaux à noyau à 12 chaînons.
