RECOVERY PROCESS OF SYSTEMS ANALYSIS OF IRON OXIDE IN THE WATER GAS ATMOSPHERE IN THE PRESENCE OF CARBON

Abstract

The parameters of equilibrium in a process of reduction of iron oxides with water gas (CO – CO2 – H2 – H2O) in a presence of carbon are cal- culated. For the first time the graphical presentations of the results contain space diagram, consisted of combination of surfaces of three phase equi- libriums, lines of four phase equilibriums, and point of nonvariant five phase equilibrium obtained as an intersection of abovementioned lines. The equilibrium water gas compositions above the mixtures of Fe3O4 – C, Fe3O4 – FeO – C, FeO – C, FeO – Fe(С) – C, Fe(С) – C and Fe3O4 – Fe(С) – C are established. The graphical method for determination of water gas compositions above these mixtures is proposed.
