In this work, for the first time, iron ores with 91.7%–96.2% Fe2O3, 1.3%–2.3% Al2O3, 1.2%–4.5% SiO2, 1.3%–3.9% Na2O, were studied directly as bulk catalysts for methane decomposition. By hydrogen pre-reduction at 850 °C, Fe2O3 species on iro

The presence of a Fe-FeAl2 O4 structure over an Fe-Al2 O3 catalysts is demonstrated to be vital for the catalytic methane decomposition (CMD) activity. After H2 reduction at 750 °C, Fe-Al2 O3 prepared by means of a fusion method, containing 86.5 wt

The formation of a molybdenum oxycarbide active for catalytic isomerization of alkanes is strongly dependent on the total pressure of reactants. High pressures of the hydrogen/hydrocarbon mixture (up to 40 bar) increase the rate of reduction of MoO 3
