Composite materials of catalytically activated porous ceramics with molten salts were proposed for use in solar thermochemical reforming processes of methane as catalyst with high-temperature thermal storage. The high heat capacity and large latent heat (heat of solidification) of the composite molten salt at high temperatures are expected to circumvent the rapid temperature change of the catalyst...
A two-step cyclic steam reforming of methane by a WO 3 /ZrO 2 redox catalyst was performed to produce CO-rich syngas and hydrogen. The two-step cyclic processes could be repeated using a redox system of WO 3 below 1273 K. The produced CO-rich syngas had the H 2 /CO ratios of about two, which was suitable for methanol production. This endothermic syngas-production process...
The methane reforming process combined with metal-oxide reduction was examined on iron-based oxides of Ni(II)-, Zn(II)-, and Co(II)-ferrites, for the purpose of converting solar high-temperature heat to chemical fuels of CO-rich syngas and reduced metal oxide as storage and transport of solar energy. It was found that the Ni(II)-doping effectively improves the reactivity of magnetite as an oxidant...
