A process of preparation a catalyst for medium temperature conversion of carbon oxide (II) with water steam includes precipitation of initial salts of ferrum, chromium and cuprum by solution of carbonate, tableting and baking of catalytic mass. As initial salts of ferrum, chromium and cuprum chlorides of these metals are used, while as precipitator ammonium carbonate is used, moreover joint precipitation of components is carried out at a temperature of 303±2 K, and the mass is baked according to the scheme: temperature rise from 293 to 613 K at a rate of 5-10 deg./min, holding at 613 K during 45-60 minutes, rise of temperature from 613 to 673 K at a rate of 10 deg./min, holding at a temperature of 673 K during 1.8-2.0 hours. |
