К термодинамике процессов восстановления оксидов железа в атмосфере водяного газа

Abstract

Построена пространственная диаграмма фазовых равновесий, реализующихся при восстановлении оксидов железа в атмосфере водяного газа (СО – СО2 – Н2 – Н2О). Установлены параметры газовой фазы устойчивого существования твердых Fe3O4, FeO и Fe, рассчитаны поверхности трехфазных равновесий и линия четырехфазного равновесия. Разработан метод графического определения возможных составов водяного газа с оксидами железа. The space (3-dimensional) diagram of phase equilibriums at the reduction of iron oxides with water gas (CO-H2-H2O-CO2) is constructed.. The gas phase parameters needed for thermodynamically stable existence of solid Fe3O4, FeO or Fe with gas phase are established. The surfaces of three-phase equilibriums and multi-dimensional (3-dimensional) lines of four-phase equilibriums are calculated. The method for graphical estimation of possible water gas composition being in equilibrium with iron oxides is developed.
