This invention relates to the catalyst composition resulting from the addition of phosphorus, and optionally, a matrix material, to a porous crystalline material having the structure of MCM-22. The addition of phosphorus to the MCM-22 is found to improve the hydrothermal stability of the resulting catalyst. The improved catalyst is useful in organic conversion processes, e.g., catalytic cracking processes. Cette invention concerne une composition de catalyseur qu'on produit en ajoutant du phosphore et, facultativement, une matière matricielle dans une matière cristalline poreuse présentant la structure de la zéolite MCM-22. On a découvert que le fait d'ajouter du phosphore dans la zéolite MCM-22 améliore la stabilité hydrothermique du catalyseur résultant. Ce catalyseur amélioré est utile dans des procédés de conversion organique tels que des procédés de craquage catalytique.
