Reduction of Iron Oxides with Hydrogen—A Review
Iron oxide reduction is a complex process due to many parameters that have an influence on the reduction rate. Single mechanisms occurring during reduction are well known. The problem is the combination of different steps where the combination strongly depends on the process concept the reduction parameters and the input material.
