A composition for passivating metal contaminants in catalytic cracking of hydrocarbons includes a non-layered, ultra-large pore crystalline material with at least one peak at a position greater than about 18 Angstrom Units d- spacing with a relative intensity of 100, and a benzene adsorption capacity of greater than about 15 grams benzene per 100 grams anhydrous crystal at 50 torr and 25 ~C, and a metal passivator incorporated within the crystalline material. A method for passivating contaminating metals uses the composition during catalytic cracking as an additive or as a component of the catalyst.
L'invention concerne une composition destinée à passiver des contaminants métalliques lors du craquage catalytique d'hydrocarbures, qui comprend un matériau cristallin à pores ultragrands, sans couches, présentant au moins une crête en un point supérieur à l'espacement d d'environ 18 angströms dont l'intensité relative est de 100 et une capacité d'adsorption de benzène supérieure à environ 15 grammes de benzène pour 100 grammes de cristal anhydre à 50 torrs et 25 ·C, et un agent de passivation des métaux incorporé dans le matériau cristallin. Dans un procédé de passivation des métaux contaminants, ladite composition est utilisée pendant le craquage catalytique comme additif ou composant du catalyseur.
