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 conversion of phenol into CO, CO 2 and H 2 by steam reforming over La-containing supported Rh catalysts
Constantinou, D. A.; álvarez-Galván, M. C.; Fierro, José Luis García; Efstathiou, Angelos M. (2012)The steam reforming of phenol in the low-temperature range of 350-550°C was studied over 0.5wt% Rh supported on Ce 0.15Zr 0.85O 2, Zr 0.93La 0.07O 2, and Ce 0.13Zr 0.83La 0.04O 2 mixed metal oxides. The reforming specific ...

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 ...

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. ...

Surface reactivity of LaCoO3 and Ru/LaCoO3 towards CO, CO2 and C3H8: Effect of H2 and O2 pretreatments
Álvarez-Galván, M. C.; Constantinou, D. A.; Navarro, R. M.; Villoria, J. A.; Fierro, José Luis García; Efstathiou, Angelos M. (2011)The differences in surface reactivity of LaCoO3 and Ru/LaCoO3 solids after pre-treatment in a hydrogen or oxygen gas atmosphere towards oxidative steam reforming (OSR) of propane was probed by performing temperature-programmed ...
