Patent
CA 2419253
A catalyst component, a catalyst, and a process for making the component and catalyst are disclosed herein. Also disclosed herein is a fluid catalytic cracking process for converting petroleum feedstocks to lower boiling products wherein the feedstock is contacted with the catalyst. The catalyst component is a crystalline microporous oxide catalyst to which a compound for promoting dehydrogenation and increasing lewis acidity is effectively added. This catalyst component ca be included in an inorganic oxide matrix material and used as a catalyst. Preferably, the compound for promoting dehydrogenation and increasing Lewis acidity is effectively added to a non-framework portion of the crystalline microporous oxide.
L'invention concerne un composant catalytique, un catalyseur, et un procédé relatif à l'élaboration du composant catalytique et du catalyseur. L'invention concerne également un procédé de craquage catalytique fluide permettant de convertir des charges de pétrole en produits à point d'ébullition inférieur, qui consistent à mettre ces charges en contact avec le catalyseur. Le composant catalytique est un catalyseur à l'oxyde cristallin microporeux auquel on ajoute efficacement un composé favorisant la déshydrogénation et augmentant l'acidité de Lewis. Ce composant peut être intégré à un matériau à matrice d'oxyde inorganique et utilisé comme catalyseur. De préférence, le composé qui favorise la déshydrogénation et augmente l'acidité de Lewis est ajouté efficacement à une partie de l'oxyde cristallin microporeux ne constituant pas l'édifice structural de cet oxyde.
