Patent

CA 2451667

The invention relates to a molecular sieve catalyst composition, to a method of making or forming the molecular sieve catalyst composition, and to a conversion process using the catalyst composition. In particular, the invention is directed to making a formulated molecular sieve catalyst composition from a slurry of formulation composition of a synthesized molecular sieve that has not been fully dried, a binder and an optional matrix material. In a more preferred embodiment, the weight ratio of the binder to the molecular sieve and/or the solid content of the slurry is controlled to provide an improved attrition resistant catalyst composition, particularly useful in a conversion process for producing olefin(s), preferably ethylene and/or propylene, from a feedstock, preferably an oxygenated containing feedstock.

L'invention concerne une composition de catalyse à tamis moléculaire, un procédé de fabrication ou d'élaboration de ladite composition de catalyse ainsi qu'un procédé de conversion utilisant ladite composition de catalyse. D'une manière plus spécifique, l'invention concerne la fabrication d'une composition formulée de catalyse à tamis moléculaire à partir d'une suspension de la formulation d'un tamis moléculaire synthétisé qui n'a pas été complètement séché, d'un liant et d'un matériau de matrice optionnel. Dans un mode de réalisation idéal, le rapport pondéral entre le liant et le tamis moléculaire et/ou le contenu solide de la suspension est régulé afin d'obtenir une composition de catalyse améliorée résistante à l'attrition, particulièrement utile dans un procédé de conversion pour la production d'oléfines, de préférence éthylène et/ou propylène, à partir d'une charge d'alimentation, de préférence une charge contenant un composé oxygéné.
