ABSTRACT:
Process for the preparation of a crystalline aluminosilicate enriched in silica, having the structure of mazzite, by hydrothermal crystallization of a gel containing sources of silicon, aluminum and alkali metal ions, in the presence of an organic structuring agent, characterized in that the source of aluminum is a zeolite Y in the form of spheres. The mazzite obtained does not contain any silicoalumina debris out of the lattice. It is employed as catalyst for the conversion of hydrocarbons or as molecular sieve.
