FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry and catalyst systems which can be used particularly in processes for oxidation of hydrogen chloride to molecular chlorine, oxychlorination of methane, partial oxidation of (C₁-C₄) lower paraffins to alcohols and aldehydes (oxygenates). The invention can also be used in processes for producing valuable chemical products and semi-products, as well as when processing different gaseous and liquid wastes. Described is a catalyst system for heterogeneous reactions, which is a geometrically structured system containing microfibre of a high-silica carrier with diameter of 5-20 mcm, which is characterised by presence of hydroxyl group absorption bands in the infrared spectrum with wave number ν=3620-3650 cm^-1 and half-width 65-75 cm^-1, has specific surface area measured using a BET method based on thermal desorption of argon, S_Ar=0.5-30 m²/g, has surface area measured using an alkaline titration method S_Na=5-150 m²/g with ratio S_Na/S_Ar=5-50, and at least one active element, characterised by that the active element is made either in form of a Me_zO_xHal_y composite or in form of a N_wMe_zO_xHal_y composite, where element N in the composite N_wMe_zO_xHal_y is selected from a group comprising alkali, alkali-earth elements or hydrogen, element Me in composite N_wMe_zO_xHal_y and composite Me_zO_xHal_y is selected from a group containing iron, cobalt, nickel, ruthenium, rhodium, vanadium, chromium, manganese, zinc, copper, silver, gold, or one element from lanthanum and lanthanides, and element Hal in composite N_wMe_zO_xHal_y and composite Me_zO_xHal_y is one of halogens: fluorine, chlorine, bromine and iodine.

EFFECT: higher activity of the catalyst system and high resistance to deactivation in aggressive media in oxidation, chlorination and oxychlorination reactions.
