ABSTRACT:
Comminuted iron ore, which may be pre-reduced partly or wholly if desired, is flash smelted in a vertical shaft furnace with excess carbon, and off gases are produced from which a large amount of hydrogen is recovered. The major portion of hydrogen is a product gas which can be used for reactions, such as the production of ammonia, hydrogenation of coal, and the like, or it may be used as a cooling agent for electric generators and the like.
