METHOD OF PREPARING CATALYST FOR MIDDLE-TEMPERATURE STEAM-MEDIATED CONVERSION OF CARBON MONOXIDE Russian patent published in 2007 - IPC B01J37/04 B01J23/745 B01J23/72 B01J23/78 

FIELD: carbon monoxide conversion catalysts.

SUBSTANCE: preparation of middle-temperature carbon monoxide conversion catalysts, which can be used in industrial production of ammonia synthesis destined nitrogen-hydrogen mixture, comprises mechanical activation of iron-containing component with calcium and copper oxides, mixing with water to form plastic mass, extrusion forming, drying, and calcination, said iron-containing component being iron metal powder and said mechanical activation of components being accomplished by passing air enriched with oxygen to 30-100%. Under these circumstances, catalyst activity rises by 19.4-23.1%.

EFFECT: increased catalyst activity, eliminated formation of waste waters and emission of toxic nitrogen oxides, and reduced (by 30%) number of process stages.
