FIELD: chemistry.

SUBSTANCE: invention relates to a layered composition, a method of preparing the said composition and a method of converting hydrocarbon using the said composition. Described is a layered composition for use in catalysts, having an inner core selected from a group consisting of aluminium oxides, cordierite, mullite, montmorillonite, silicon dioxide, zirconium oxide, titanium oxide, silicon carbide and mixtures thereof, and having form selected from a group consisting of granules, extrudates, spheres, hollow tubes, or irregularly shaped particles, and an outer layer over the inner core, which contains a heat resistant inorganic oxide different from the heat resistant oxide of the inner core, a fibre component selected from a group comprising fibre from titanium oxide, fibre from zirconium oxide or fibre from mullite, and an inorganic binder. The layered composition is obtained by depositing a coating onto an inner core using a suspension which contains a heat resistant inorganic oxide, a fibre component, an inorganic binder precursor, organic binding agent and a solvent, with formation of a coated core and subsequent calcination at temperature not below 200°C. The composition can be used in different hydrocarbon conversion processes.

EFFECT: increased in strength of the composition.
