Abstract

See full text

In various exemplary embodiments, the present invention provides systems and methods that can convert clean or raw natural gas, clean or dirty coke oven gas, or the like to reducing gas/syngas suitable for direct reduction with minimal processing or cleaning. Hydrocarbons and the like are converted to H2 and CO. S does not affect the conversion to reducing gas/syngas, but is removed or otherwise cleaned up by the iron bed in the direct reduction shaft furnace. Top gas may be continuously recycled or a once-through approach may be employed.
