New insights into the role of the electronic properties of oxide promoters in Rh-catalyzed selective synthesis of oxygenates from synthesis gas
(2011-06-13)
Article
Accés restringit per política de l'editorialA series of 2.5% Rh/M@Al2O3 model catalysts were prepared by supporting Rh on high-area c-Al2O3, resulting in a surface covered by a monolayer (4.5–7 atoms/nm2) of MOx promoter oxides (M = Fe, V,Nb, Ta, Ti, Y, Pr, Nd,Sm). ... -
Partial oxidation of methane to syngas using Co/Mg and Co/Mg-Al oxide supported catalysts
(2018-04-03)
Article
Accés obertPartial oxidation of methane (POM) was studied over a series of Co/Mg-Al catalysts. Various commercial hydroxides with different Mg/Al ratios were used as precursors of the oxides employed as catalytic supports, as well ... -
Simulation of two-step redox recycling of non-stoichiometric ceria with thermochemical dissociation of CO 2 /H 2 O in moving bed reactors – Part I: Model development with redox kinetics and sensitivity analysis
(2019-03-29)
Article
Accés obertChemical looping syngas production is a two-step process that produces CO and H2 from water and CO2 splitting. This is performed by exploiting a metal oxide as oxygen carrier material, which is thermally reduced and releases ... -
System efficiency analysis of dual interconnected bubbling fluidized bed reactors for solar fuel production
(Universidade do Minho, 2019-08-19)
Text en actes de congrés
Accés obertChemical looping syngas production is a two-step syngas fuel production process that produces CO and H 2 . The process is composed of two fluidized bed reactors (oxidation reaction and reduction reactor), oxygen carriers ... -
Techno-economic and exergy analysis of polygeneration plant for power and DME production with the integration of chemical looping CO 2 /H 2 O splitting
(Elsevier, 2019-04-15)
Article
Accés obertIn this paper, we present a novel polygeneration plant with carbon capture for the combined power and dimethyl ether (DME) production. The plant layout integrates a chemical looping CO2/H2O splitting (CL) unit producing ... -
The effect of Fe-Rh alloying on CO hydrogenation to C2+ oxygenates
(2015-09-01)
Article
Accés obertA combination of reactivity and structural studies using X-ray diffraction (XRD), pair distribution function (PDF), and transmission electron microscopy (TEM) was used to identify the active phases of Fe-modified Rh/TiO2 ... -
Thermodynamic assessment of non-catalytic Ceria for syngas production by methane reduction and CO2 + H2O oxidation
(2019-03-01)
Article
Accés obertChemical looping syngas production is a two-step redox cycle with oxygen carriers (metal oxides) circulating between two interconnected reactors. In this paper, the performance of pure CeO2/Ce2O3 redox pair was investigated ...
