TL;DR: Two-step solar thermochemical cycles and processes for the production of hydrogen, hydrocarbons, and synthesis gas are considered in this paper, where the thermodynamics of both reaction steps are examined and relevant experimental studies conducted using solar energy are reviewed.

TL;DR: In this article, the authors presented a thermochemical process that uses concentrated solar radiation as the energy source of high-temperature process heat, where the chemical equilibrium components consist of metallic iron in the solid phase and a mixture of 667% H 2 and 333% CO in the gaseous phase.

TL;DR: In this paper, the combined thermal reduction of ZnO and reforming of CH4 has been thermodynamically and kinetically examined, and the reaction mechanism was found to be controlled by gas film diffusion in the Stokes regime.

TL;DR: In this article, a tubular fixed bed reactor at various temperatures was used to study the reaction of the non-stoichiometric iron oxide Fe1−yO and mixed iron manganese oxides (Fe1−xMnx)1−YO (x ≤ 0.3) by water.
