FIELD: chemistry.
SUBSTANCE: invention refers to the preparation of molecular sieves. The claimed method comprises the preparation of laminar composition including the inner seed domain and outer layer containing the molecular sieve. The said method includes provision of the suspension containing the particles of the inner seed domains and the sources of the elements of molecular sieve lattice. The starting materials that is the elements sources are added to the said suspension whereby the crystals of molecular sieves are formed and enlarge on the inner seed domain. This process is carried out during time interval enough for forming of the layer with desired thickness. The obtained product is used as catalyst for hydrocarbons conversion.
EFFECT: enhancing of the composition catalytical performance.
