A method for the production of the zeolites which belong to the structural family of the faujasite, resulting products and their use in adsorption and catalysis.

摘要

An aluminosilicate gel was prepared containing a structuring agent st and having an appropriate composition to be crystallized in a zeolite of the faujasite structural class, and then the said gel is subjected to a crystallization in order to form a precursor of the zeolite consisting of said zeolite containing the structuring agent in its cavities and channels, and it produces the zeolite by calcination of the precursor. / p & & p & the structuring agent st consists of at least one compound chosen from among the macrocycles and carbon-containing macropolycycles which contain, in the cycle or cycles of the heteroatoms chosen from o, n, s 1 and s and which contain 10 to 24 carbon atoms per cycle. / p & & p & the zeolites obtained have a ratio si: a1 greater than 1 and which may exceed 3 and having, according to the nature of st, a structure of cubic symmetry or of hexagonal symmetry. These zeolites are used, either directly or after cation exchange, as adsorbents or as components of catalysts.
