Hydrogen gas and its use in Iron and Steel industry

14-01-2019· Hydrogen reduction processes There are several hydrogen reduction processes for the iron ore as described below. Shaft furnaces are used for the reduction of iron ore pallets with reformed natural gas which is a mixture of hydrogen and carbon mono oxide. The two most relevant direct reduction processes are Midrex and Energiron (HyL-III).
