Patent

CA 2438146

The present invention relates to a silicoaluminophosphate molecular sieve comprising at least one intergrown phase of molecular sieves having AEI and CHA framework types, wherein said intergrown phase has an AEI/CHA ratio of from about 5/95 to 40/60 as determined by DIFFaX analysis, using the powder X- ray diffraction pattern of a calcined sample of said silicoaluminophosphate molecular sieve. It also relates to methods for its preparation and to its use in the catalytic conversion of methanol to olefins.

L'invention concerne un tamis moléculaire en silicoaluminophosphate comprenant au moins une phase entremêlée de tamis moléculaires possédant des types de cadre AEI et CHA, la phase entremêlée ayant un rapport AEI/CHA compris entre environ 5/95 et 40/60, tel que déterminé par une analyse DIFFaX, au moyen du motif de diffraction de rayon X sur poudre, d'un échantillon calciné du tamis moléculaire en silicoaluminophosphate. L'invention concerne également des procédés de préparation et d'utilisation de celui-ci dans la conversion catalytique de méthanol en oléfines.
