Zusammenfassung:FIELD: production and use of high-silica alumo-silicate zeolite. ^ SUBSTANCE: proposed high-silica zeolite is used as absorbents and catalysts. Proposed zeolite is produced by hydro-thermal crystallization of reaction mix at temperature of 150-180°C continued for 2-7 days; reaction mix contains source of silicon oxide, aluminum oxide, alkaline metal cations, zeolite "seed", organic structure-forming additive and water; it has the following chemical composition at molar ratio: SiO2/Al2O3 = 20-100; Na+/SiO2 = 0.1-1.0; OH-/SiO2 = 0.1-1.0; H2O/SiO2 = 10-100 and mass ratio R/SiO2 = 0.03-1.0. Used as organic structure-forming additive (R) is "X-oil" fraction -waste of caprolactam production process. Synthetic alumo-silicate zeolites which have structure of type MF1 zeolites and are prepared according to the proposed method with the use of organic structure-forming additive - "X-oil" fraction may be used for production on their base of highly effective catalysts for various reactions of conversion of hydrocarbons. ^ EFFECT: enhanced efficiency. ^ 3 cl, 4 tbl, 8 ex
