  • Ilmenite Reduction Lunarpedia

    Hydrogen reduction is one method currently being tested by many Universities. Products of hydrogen reduction are free iron, titanium dioxide (TiO 2), and water, which is split to recover the hydrogen and produce oxygen.. The basic process is to separate ilmenite from lunar soil, crush it to a fine powder to maximize the surface area, and then heat it in an enclosed reaction vessel in the

  • Behavior of ilmenite as oxygen carrier in chemical-looping

    2/1/2012· Ilmenite is a common mineral found in metamorphic and igneous rocks. The ilmenite used is a concentrate from a natural ore. Fresh particles have been exposed to thermal pre-treatment at 950 °C in air during 24 h, since it improves its performance as oxygen-carrier,. Table 1 shows the main properties for calcined ilmenite. The XRD analysis of calcined ilmenite revealed that Fe 2 TiO 5 and

    6/25/2017· The FeO content is an important quality index of reduced ilmenite, and the relationship between FeO content and Fe–Si dosage are shown in Fig. 7. The FeO content of reduced ilmenite decreases progressively with the increase in reduction time. With the increasing Fe–Si dosage from 0% to 3%, the FeO content accordingly decreases.

    2/15/2011· The oxygen transport capacity of ilmenite R o,ilm was calculated as (3) R o, i l m = m o − m r m o where m o and m r are the mass of the most oxidized and reduced form of the oxygen carrier, respectively. In the CLC process, pseudobrookite (Fe 2 TiO 5) and hematite (Fe 2 O 3) are reduced to ilmenite (FeTiO 3) and magnetite (Fe 3 O 4), respectively.Rutile is considered to be an inert.
