Qısa məlumat

Areas of uncertainty in the thermodynamic parameters of oxidative reduction reactions of titanomagnetite concentrates were identified using the universal genetic algorithm (MGA). The oxidative reduction reactions of titanomagnetite concentrates for the production of iron, titanium dioxide and sodium vnadate in a reactor flow mode, with a change in the composition and pressure of the reaction products, have been investigated. To determine the temperature dependences of the Gibbs free energy of oxidative reduction reactions in the temperature range 900–1400 K, the Temkin-Shvartsman equation was used, modified taking into account the thermodynamic functions of the formation of solid solutions and the value of the vapor pressure of gaseous components. It was revealed that the ranges of temperature and pressure uncertainty for direct reduction of Fe3O4 to free iron, oxidation of V3+ to V5+ in granules of titanomagnetite concentrates are: P = 0.1 ÷ 1 atm, T = 1000 ÷ 1400K.
