SUMMARY:Green methanol as CO2 lean reductant for iron ore
DESCRIPTION:The use of green H2 as reductant shall lead to a CO2 lean ironmaking. The industrial demand of green H2 in the future cannot be supplied via own resources and must therefore be imported from regions with better prerequisites for green H2 as well as renewable electricity production e.g. MENA region. The problem to transport such big amounts of green H2 shall be solved by using liquid ammonia (NH3) as H2-carrier. One missing link in this H2 transportation chain is the availability of an industrial proven solution for the NH3-splitting to recover the H2. This is still under development. Using green methanol (MeOH) as H2 carrier does not have this problem, because industrial proven solutions exist for all parts of the H2 transportation chain as well as the chain closing the CO2 cycle related to green MeOH production and its use. Moreover 1 m³ of MeOH lead stoichiometrically to 148 kg of H2, whereas 1 m³ liquid NH3 lead stoichiometrically to 107 kg of H2.
Besides that, MeOH is an interesting reductant for iron oxides due to its physical and chemical properties. Under normal conditions it is a liquid. Its boiling temperature is 65°C, which makes it applicable to vaporize with low temperature waste heat. Methanol vapor is chemically adsorbed on the surface of hematitic as well as magnetitic iron oxides. At about 320°C it causes a reduction to ferrous oxide FeO, H2 and CO2 as reaction products leading to a new concept for DRI production.
