Generation Behavior of H_2 Gas by Reaction between FeO-containing Slag and H_2O-Ar Gas

摘要

Generation behavior of H_2 gas by reaction between FeO-containing slag and H_2O~Ar gas was measured at 1 723 K with four kinds of synthesized FeO-CaO-SiO_2-Al_2O_3-MgO-P_2O_5 slag. From 32.2 to 50.5% of FeO contained in slags were oxidized to Fe_2O_3 by 0.086 atm H_2O-Ar gas for 120 min. Maximal amount of generated H_2 gas estimated from composition change was 0.59 mol-H_2/kg-slag for 120 min at present experimental conditions.
