Cobalt hydrotalcites as catalysts for bioethanol steam reforming. The promoting effect of potassium on catalyst activity and long-term stability
(2012-10-30)
Article
Restricted access - publisher's policyCobalt hydrotalcite-derived catalysts, doped with potassium, are active materials for the ethanol steam reforming reaction. Potassium addition reduces the acid sites number and strength. It acts as a promoter of the ethanol ... -
Ethanol steam reforming over hydrotalcite-derived Co catalysts doped with Pt and Rh
(2013-12)
Article
Restricted access - publisher's policyHoneycomb structures loaded with hydrotalcite-derived cobalt catalysts doped with various amounts of Pt and Rh have been tested in the steam reforming of ethanol at 523-823 K under different operational conditions. Catalysts ... -
PdCu alloy nanoparticles on alumina as selective catalysts for trichloroethylene hydrodechlorination to ethylene
(2013-02-26)
Article
Restricted access - publisher's policyPdCu bimetallic catalysts supported on alumina were prepared by different common impregnation protocols and by a polyol nanoparticles synthesis route. These materials were studied in order to establish the relationship ... -
Precisión en la discretización de problemas unidimensionales de propagación de ondas
(Centro Internacional de Métodos Numéricos en Ingeniería, 1986)
Article
Open AccessSe presenta un estudio de la precisión del método de elementos finitos en discretizaciones que modelan problemas de propagación de ondas. Con discretizaciones de elementos finitos de tamaño constante se obtienen curvas de ... -
Pt-Ag/activated carbon catalysts for water denitration in a continuous reactor: Incidence of the metal loading, Pt/Ag atomic ratio and Pt metal precursor
(2012-10-30)
Article
Restricted access - publisher's policySeveral Pt–Ag catalysts supported on activated carbon powder were tested in the catalytic reduction of nitrates in a continuous flow reactor. The influence of the noble metal precursor (Pt(NH3)4(NO3)2 or H2PtCl6), the Pt/Ag ... -
Stability of ruthenium catalysts supported by aerogel mixed oxides during the wet air oxidation of p-hydroxybenzoic acid in a continuous reactor
(2012-12)
Article
Restricted access - publisher's policyContinuous catalytic wet air oxidation was investigated as a suitable treatment of p-hydroxybenzoic acid chosen as a phenolic compound typically found in olive mill wastewater. The reaction was conducted in a continuous ... -
Synthesis and characterization of poly-l-leucine initialized and immobilized by rehydrated hydrotalcite: Understanding stability and the nature of interaction
(2013-10-07)
Article
Restricted access - publisher's policyPLLs were synthesized by the ring-opening polycondensation (ROP) method using α-L-leucine N-carboxyanhydride (NCA) and initialized by triethylamine (Et3N), water or rehydrated hydrotalcite (HTrus). The role of temperature, ...
