Catalysts and conditions in the oxidative steam reforming of bio-oil for stable H2 production
(2018-06-28)
Se ha estudiado la producción de H2 mediante reformado oxidativo (OSR) de bio-oil, un proceso catalítico alternativo y más económico respecto del convencional reformado con vapor. Para los ensayos cinéticos se ha empleado ...
Surface Characterization of Mesoporous CoOx/SBA-15 Catalyst upon 1,2-Dichloropropane Oxidation
(MDPI, 2018-06)
The active combustion catalyst that is based on 30 wt % cobalt oxide on mesoporous SBA-15 has been tested in 1,2-dichloropropane oxidation and is characterized by means of FT-IR (Fourier transform infrared spectroscopy) ...
Effect of Residual Na+ on the Combustion of Methane over Co3O4 Bulk Catalysts Prepared by Precipitation
(MDPI, 2018-09-29)
The effect of the presence of residual sodium (0.4 %wt) over a Co3O4 bulk catalyst for methane combustion was studied. Two samples, with and without residual sodium, were synthesized by precipitation and thoroughly ...
Capability of the Direct Dimethyl Ether Synthesis Process for tCapability of the Direct Dimethyl Ether Synthesis Process for the Conversion of Carbon Dioxide
(MDPI, 2018-05)
The direct synthesis of dimethyl ether (DME) is an ideal process to achieve the environmental objective of CO2 conversion together with the economic objective of DME production. The effect of the reaction conditions ...
Oxidative Steam Reforming of Raw Bio-Oil over Supported and Bulk Ni Catalysts for Hydrogen Production
(MDPI, 2018-08)
Several Ni catalysts of supported (on La2O3-alpha Al2O3, CeO2, and CeO2-ZrO2) or bulk types (Ni-La perovskites and NiAl2O4 spinel) have been tested in the oxidative steam reforming (OSR) of raw bio-oil, and special attention ...
Valorisation of secondary streams, tyres and plastics in the Waste-Refinery
(2018-06-25)
Se ha estudiado la valorización mediante hidroprocesado de una corriente de refinería de interés secundario (aceite de ciclo ligero, LCO) y de dos alimentaciones derivadas de los residuos de consumo, como son el líquido ...
Cobalt aluminate spinel-derived catalysts for glycerol aqueous phase reforming
(Elsevier, 2018-08-02)
Catalytic activity at mild (235 °C/3.5 MPa) and severe (260 °C/5.0 MPa) APR conditions was investigated over catalysts based on cobalt aluminate spinel synthetized by coprecipitation. Co/Al ratio was varied and physicochemical ...
Nickel aluminate spinel-derived catalysts for the aqueous phase reforming of glycerol: Effect of reduction temperature
(Elsevier B.V., 2018-12-07)
Bulk nickel aluminate (NiAl2O4) was synthesised by co-precipitation at a Ni/Al mole ratio of 1:2 (stoichiometric ratio). The prepared sample was reduced at different temperatures, in the 300 to 850 ºC range, and obtained ...
Oxidation of residual methane from VNG vehicles over Co3O4-based catalysts: Comparison among bulk, Al2O3-supported and Ce-doped catalysts
(Elsevier, 2018-06-20)
Cobalt oxide based catalysts with three different active phase configurations, namely bulk, alumina supported and cerium-doped Co3O4 samples were examined for the complete oxidation of methane under conditions similar to ...
Behaviour of Rh supported on hydroxyapatite catalysts in partial oxidation and steam reforming of methane: On the role of the speciation of the Rh particles
(Elsevier, 2018-03-04)
Rh/hydroxyapatite samples were prepared by impregnation and investigated for the partial oxidation (POM) and steam reforming (SRM) of methane. The catalysts were analysed by BET, XRD, DRS, XPS, H 2 -TPR, TEM, H2 chemisorption, ...
