The phenol steam reforming reaction towards H2 production on natural calcite
(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 ...

A preliminary study of combining mass spectrometric data with audio and video signals for real-time monitoring of controlled lab-scale fires
(2011)The different aspects of sensors integration, and specifically that of a Mass Spectrometer (MS) with audio and video signals, are investigated for detecting and monitoring indoor fire events. The present study focuses on ...

Rates of activation and scanning electron microscopy of polyarylamide-derived chars
(1995)Fibrous activated carbons were prepared from Kevlar® (poly (p-phenylene terephthalamide)) and Nomex® (poly (m-phenylene isophthalamide)) by carbonisation in nitrogen and subsequent activation in steam of carbon dioxide to ...

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

Solvothermal synthesis, nanostructural characterization and gas cryo-adsorption studies in a metal–organic framework (IRMOF-1) material
(2017)A nanoporous metal–organic framework material, exhibiting an IRMOF-1 type crystalline structure, was prepared by following a direct solvothermal synthesis approach, using zinc nitrate and terephthalic acid as precursors ...

Spectroscopic investigations on the effect of humic acid on the formation and solubility of secondary solid phases of Ln2(CO3) 3
(2011)The formation of secondary Ln(III) solid phases (e.g., Nd 2(CO3)3 and Sm2(CO3) 3) was studied as a function of the humic acid concentration in 0.1 mol/L NaClO4 aqueous solution in the neutral pH range (5-6.5). The solid ...

Trade-offs in CO2-oriented vehicle tax reforms: A case study of Greece
(2012)We estimate demand for automobiles in Greece using a model of product differentiation and use the model to evaluate carbon-based tax schemes that could shift consumer purchases towards low CO2 emission cars. We find that ...

Water-gas shift reaction on Pt/Ce1- xTixO 2-δ: The effect of Ce/Ti ratio
(2013)Pt nanoparticles (1.2-2.0 nm size) supported on Ce1-xTi xO2-δ (x = 0, 0.2, 0.5, 0.8, and 1.0) carriers synthesized by the citrate sol-gel method were tested toward the water-gas shift (WGS) reaction in the 200-350 C range. ...
