Title
(EN) A ZEOLITE FAMILY BUILT FROM A FRAMEWORK BUILDING LAYER
(FR) FAMILLE DE ZEOLITES FORMEE A PARTIR D'UNE COUCHE D'AGENCEMENT DE STRUCTURE
Abstract
(EN)
The present invention is a structure comprising, a basic zeolite framework building layer. The zeolite framework building layer is built of tetrahedra formed by oxygen atoms where a T-atom is at the center of each tetrahedron. The TO4 tetrahedra are connected through their vertices to form a layer that contains 4-, 5- and 12-rings. A ring is defined by the number of T-atoms forming the rings. The layer can be described as chains of alternating 4- and 5-rings of TO4 tetrahedra. The neighboring 5-rings in each chain are pointing in opposite directions and further connect to the 5-rings from another chain through vertex-sharing of oxygen atoms to form a layer containing 12-rings. The unconnected oxygen in the tetrahedra can be either pointing up or down with respect to the layer.

La présente invention se rapporte à une structure contenant une couche de base d'agencement de structure zéolite. La couche d'agencement de structure zéolite est formée de tétraèdres constitués d'atomes d'oxygène, un atome de T se trouvant au centre de chaque tétraèdre. Les tétraèdres de TO4 sont reliés par leurs sommets de manière à former une couche contenant des cycles quadrangulaires, pentagonaux et dodécagonaux. Un cycle est défini par le nombre d'atomes de T qui le forment. La couche peut se présenter sous forme de chaînes constituées d'une alternance de cycles quadrangulaires et pentagonaux des tétraèdres de TO4. Les cycles pentagonaux voisins dans chaque chaîne sont orientés dans des directions opposées, et sont en outre reliés aux cycles pentagonaux d'une autre chaîne par le partage, au niveau de leurs sommets, d'atomes d'oxygène, ce qui permet de former une couche contenant des cycles dodécagonaux. L'oxygène non relié dans le tétraèdre peut être orienté soit vers le haut soit vers le bas par rapport à ladite couche.
