A comparative study of the steam reforming of phenol towards H2 production over natural calcite, dolomite and olivine materials

Constantinou, D. A.; Fierro, José Luis García; Efstathiou, Angelos M. (2010)

Pre-calcined (air, 850 °C) naturally occurring calcite, dolomite and olivine materials were studied for phenol steam reforming towards H2 production. The effect of reaction temperature, feed volume flow rate, and hydrogen ...

Low-temperature purification of gas streams from phenol by steam reforming over novel supported-Rh catalysts

Constantinou, D. A.; Efstathiou, Angelos M. (2010)

The purification of gas streams from phenol at low-temperatures (350-550 °C) was investigated by its reaction with steam over novel catalytic systems, namely 0.5 wt% Rh supported on Ce0.15Zr0.85O2, Ce0.15Zr0.83Mg0.02O2 and ...

The phenol steam reforming reaction towards H2 production on natural calcite

Constantinou, D. A.; Fierro, José Luis García; Efstathiou, Angelos M. (2009)

The steam reforming of phenol towards H2 production was studied in the 650-800 °C range over a natural pre-calcined (air, 850 °C) calcite material. The effects of reaction temperature, water, hydrogen, and carbon dioxide ...

Reforming of methane with carbon dioxide to synthesis gas over supported Rh catalysts

Tsipouriari, Vaso A.; Efstathiou, Angelos M.; Zhang, Z. L.; Verykios, Xenophon E. (1994)

Reforming of methane with carbon dioxide to synthesis gas (CO/H2) has been investigated over rhodium supported on SiO2, TiO2, γ-Al2O3, MgO, CeO2, and YSZ (ZrO2 (8 mol% Y2O3)) catalysts in the temperature range of 650-750°C ...

Spillover of labile OH, H, and O species in the H2 production by steam reforming of phenol over supported-Rh catalysts

Polychronopoulou, Kyriaki; Efstathiou, Angelos M. (2006)

The aim of this work was to probe the back-spillover of labile O, OH and H species during steam reforming of phenol towards H2 production in the 773-1028 K range over Rh supported on MgO and Mg-Ce-Zr-O mixed-metal oxides. ...

The steam reforming of phenol over natural calcite materials

Constantinou, D. A.; Efstathiou, Angelos M. (2009)

Five natural calcite materials of different geographical origin were studied towards the steam reforming of phenol reaction and the activity results obtained were correlated with some of their physico-chemical properties. ...
