                    Bog iron ore (I) (61.5% Fe2O3, 21.1% SiO2, and 2.9% MnO₂) and regenerated (I) were substituted for the Fe₂O₃ in the tests made at 1,100°.  At the end of 2.5 hr., about 20% CO and 45% H₂ were present in the products when (I) was used.  When a 200-gm. portion of (I) was completely reduced to metallic Fe (+impurities) and regenerated with a limited amount of O₂ (4.2-4.5 liters), less than 5% each of CH₄ and CO₂ was produced from the start, and production of CO and H₂ was fairly constant at 22-24% CO and 58-60% H₂.
