Zusammenfassung: | FIELD: shift reaction processes and catalysts. ^ SUBSTANCE: invention concerns preparing catalysts for low-temperature conversion of carbon monoxide, which catalysts can be used in industrial nitrogen-hydrogen mixture generation process for ammonia synthesis. Catalyst is prepared by mixing components containing aluminum hydroxide, copper, and zinc followed by mechanical activation, drying, and calcination of granules, wherein copper- and zinc-containing components utilized are metallic copper and zinc powders and mechanical activation of components is accomplished by passing gas mixture containing carbon dioxide, ammonia, oxygen, and water steam at molar ratio 1:(0.22-1.1):(0.12-0.35):(0.13-0.24), respectively. Catalyst activity is thus increased by 6.4 to 12.3%. ^ EFFECT: increased catalyst activity, eliminated formation of waste water, and reduced number of process operations (by a factor of two and a half). ^ 1 tbl, 3 ex |
