Cycle behaviour of iron ores in the steam-iron process

The production of pure pressurised hydrogen by the reformer-steam iron process in a fixed bed reactor system

“…Based on Eqs. (11) and (12) a calculated mass based storage density of 4.8 wt% is possible [17e19]. The third advantage is that the periodically operation of the reactor enables the production of pressurised hydrogen without an additional gas compression step.…”

Investigation of hydrogen production reaction kinetics for an iron-silica magnetically stabilized porous structure

“…In recent years, the steam iron looping process has drawn a lot of attention due to its capability to produce high purity hydrogen suitable for utilization in fuel cells and producing highly concentrated CO 2 , suitable for sequestration [1,2]. In the oxidation step of iron looping process, steam is injected into a reactor containing reduced iron to produce hydrogen and magnetite (Fe 3 O 4 ).…”

Small Scale Hydrogen Production from Metal-Metal Oxide Redox Cycles

“…Furthermore, natural ilmenite is known to react just as well with petroleum coke, syngas and methane as synthetically prepared Fe2O3/MgAl2O4 [48]. Lorente et al [49] reported a better hydrogen storage capacity and redox stability when iron ore samples was used instead of pure Fe2O3. The improvement in the overall redox performance was due to the presence of impurities including SiO2, Al2O3, MgO and CaO.…”
