Apparatus for direct reduction of iron ore containing sulfur comprises a shaft type reduction furnace with means for withdrawing two separate streams of spent reducing gas. One stream, being substantially free of sulfur is recycled through a alytic reformer to produce fresh reducing gas. The other stream containing sulfur, is connected to process equipment such as a burner where sulfur is ...

The steel industry represents about 7% of the world's anthropogenic CO2 emissions due to the high use of fossil fuels. The CO2lean direct reduction of iron ore with hydrogen is considered to offer a high potential to reduce CO2 emissions, and this direct reduction of Fe2O3 powder is investigated in this research. The H2 reduction reaction kinetics and fluidization characteristics of fine ...
