METHOD OF PRODUCING CATALYST FOR MEDIUM-TEMPERATURE STEAM CONVERSION OF CARBON MONOXIDE Russian patent published in 2025 - IPC B01J37/08 B01J37/02 B01J23/881 B01J23/885 C01B3/16 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry and specifically to a method of producing a catalyst for medium-temperature steam conversion of carbon oxide and can be used in the process of synthesis of ammonia. According to the invention, the method consists in the activation of the iron-containing component, the subsequent addition of copper dichromate, thermal treatment and moulding, wherein the iron-containing component used is hematite, which is activated with oxalic acid at a weight ratio of hematite : oxalic acid of 1:(1.1-1.2) for 30 minutes, heat treatment is carried out in a current of inert gas at a volume rate of 100 h^-1 in a drum furnace with a moving layer of material for 2 hours and moulded by pelletizing.

EFFECT: development of a method of producing a catalyst for medium-temperature steam conversion of carbon monoxide, simplification of the apparatus scheme and reduced duration of the process, high strength of the catalyst while maintaining activity.
