| Popis: | Catalytic properties and structural aspects of the formation of iron–cobalt–chromium catalysts depending on the temperature of preliminary treatment are studied. A catalytically active iron–cobalt–chromium spinel is formed at a calcination temperature of 580–600°C. If catalytic packings are overheated in the course of hydrocarbon fuel oxidation or if temperatures above 700°C are used for preliminary treatment, the catalytic activity of the samples substantially decreases because an inactive solid solution of iron and chromium oxides with corundum structures is formed. |
