The three important aspects in gas based DRI production process are (i) the molar content of H2 and CO decreases from the reduction zone bottom to its top whereas that of CO2 and H2O increases which means that inversely, the content of iron oxides decreases from top to bottom with mainly iron leaving from the shaft bottom, (ii) the solid and gas temperatures are equal along the shaft … The reactions of CO and H2O on the clean Fe(110) surface as well as surfaces with 0.25 monolayer O, OH, and H precoverage have been computed on the basis of density functional theory (GGA-PBE). In the following equation, which reactant is oxidized and which is reduced? Oxidation/Reduction Limits for H2O Consider the Oxidation of H2O to yield O2(g), the half reaction can be written as; 2 H2O === O2(g) + 4 H + + 4 e-Eo = -1.23 V (from tables) Re-writing this as a reduction (by convention) and dividing by 4 (for convenience) yields; ¼ O2(g) + H + + e-==== ½ H 2O E o = 1.23 V (note the sign change in Eo, but the magnitude remains unchanged) H2 gets oxidized to H2O (Addition of oxygen) O2 gets reduced to H2O (Addition of hydrogen) Hence, H2 … -1 There are three different versions of CO shift conversion: High temperature (HT) CO shift conversion at about 300 to 450 °C down to approx. If nothing is oxidized or reduced it is NOT redox. CI-P-0: Fe2O3 gets reduced to Fe (Removal of oxygen) CO gets oxidized to CO2 (Addition of oxygen) Hence, CO acts as reducing agent. -2.
