FIELD: chemistry.
SUBSTANCE: catalyst further comprises silicates and/or aluminosilicates in an amount of 1.0-40.0 wt %, the catalyst contains phosphorus and/or boron compounds as the oxygen-containing non-metal compounds and has the following composition, expressed as oxide, wt %: Fe2O3 - 36.0-85.0, P2O5/B2O5 - 4.0-25.0, silicates and/or aluminosilicates - 1.0-40.0. The second catalyst version further comprises at least one compound of a metal selected from the group: cobalt, manganese, zinc, chromium, copper, nickel, titanium, molybdenum, tungsten, vanadium in an amount of 0.1-30.0 wt %.
EFFECT: obtaining a catalyst which is characterized by an optimized texture, reduced bulk density, increased pore volume, and provides a high sulfur yield over a wide range of temperatures in multicomponent gas mixtures.
