PROCESS OF OXIDATING HYDROGEN SULFIDE Russian patent published in 2017 - IPC B01D53/52 B01D53/86 B01J21/02 B01J21/16 B01J27/16 C01B17/04 B01J37/04 B01J37/08 

FIELD: chemistry.

SUBSTANCE: process is carried out by passing a gas mixture comprising hydrogen sulphide and oxygen over the catalyst. The catalyst has the following composition, in terms of oxide, wt %: Fe₂O₃ (36.0-85.0); P₂O₅/B₂O₅, silicates and/or aluminosilicates (1.0-40.0). In addition, the catalyst may comprise, at least, one compound of metal selected from the group: cobalt, manganese, zinc, chromium, copper, nickel, titanium, molybdenum, tungsten, vanadium, in terms of oxide 0.1 to 30.0 wt %. The catalyst is characterized by low sensitivity to the content of water vapour and to the change in the ratio O₂/H₂S, inertness with respect to deep oxidation reactions at temperatures of 200-400°C.

EFFECT: increasing the efficiency of the sulfur recovery process from gases of various origins.
