Description	Cromium, nickel and manganese oxides have been chosen for a basic thermodynamic study on possibilities of transformation of a reducing gas ( CO, syngas, methane etc.) into hydrogen by a cyclic process based on metal oxide reduction and release of hydrogen in the next step by steam oxidation. Thermodynamics and chemical equilibrium for reduction of Cr2O3 , Mn3O4 and NiO by hydrogen, carbon monoxide, model syngas and methane and for oxidation of the relevant Cr, MnO and Ni by steam has been studied in a temperature range 400 – 1000 K.

(en) Oxidy chromu, niklu a amanganu byly vybrány pro termodynamickou studii možností transformace redukujících plynů (CO, synteticky plyn, CH4) na vodík pomocí cyklického procesu založeného na redukci oxidu kovu a na uvolnění vodíku v oxidačním kroku pomoci vodní páry. V rozmezí teplot 400 – 1000 K byly studovány termodynamika a chemické rovnováhy pro redukci Cr2O3 , Mn3O4 a NiO vodíkem , CO, syntetickým plynem, metanem a pro oxidaci relevantních produktů Cr, MnO a Ni vodní parou.
