FIELD: sorbents. SUBSTANCE: invention describes structures containing upper layer of crystalline molecular sieve on support, wherein crystals are partly oriented perpendicularly to layer plane, whereas between support and upper layer, there is dense intermediate layer of crystalline molecular sieve. Structures are useful for preparing sorbents and catalysts. EFFECT: extended assortment of intermediates for production of sorbents and catalysts. 14 cl, 9 dwg, 1 tbl
