FIELD: preparation of catalysts for petrochemical reactions. SUBSTANCE: component is characterized with X-ray pattern corresponding to silica/alumina molar ratio on the crystallite surface to be higher than or equal to the same ratio inside crystallites, and in nuclear magnetic resonance spectrum of aluminosilicate, there are -100, -106, -112, and -116 ppm lines with tetramethylsilane as reference. EFFECT: enlarged choice of catalyst components. 8 cl, 6 dwg, 11 tbl
