Hydrogen production from water electrolysis: current status and future trends
(IEEE, 2012)
Artículo / Artikulua,
This paper reviews water electrolysis technologies for hydrogen production and also surveys the state of the art of water electrolysis integration with renewable energies. First, attention is paid to the thermodynamic and ...
Influence of the power supply on the energy efficiency of an alkaline water electrolyser
(Elsevier, 2009)
Artículo / Artikulua,
Electric energy consumption represents the greatest part of the cost of the hydrogen
produced by water electrolysis. An effort is being carried out to reduce this electric
consumption and improve the global efficiency ...
Outstanding performance of rehydrated Mg-Al hydrotalcites as heterogeneous methanolysis catalysts for the synthesis of biodiesel
(Elsevier, 2018)
Artículo / Artikulua,
There is still a need for active, selective and stable heterogeneous catalysts for the synthesis of biodiesel. In this work, magnesium-aluminium hydrotalcites with Mg/Al molar ratios within the 1.5–5 range were synthesized ...
Application of eco-design and life cycle assessment standards for environmental impact reduction of an industrial product
(MDPI, 2017)
info:eu-repo/semantics/article,
Eco-design is included within the framework of the standard for “Environmental management systems—Guidelines for incorporating Eco-design” (ISO 14006:2011). Eco-design process, as defined in standard, has six steps: (i) ...
Rutas y retos para la valorización de biogás
(Universidad Libre (Colombia), 2017)
info:eu-repo/semantics/article,
Las tecnologías de digestión anaerobia para procesar corrientes residuales (fracción orgánica de residuos de vertedero, lodos de estaciones depuradoras de aguas residuales, purines, etc.) han originado un incremento de ...
Kinetic analysis and CFD simulations of the photocatalytic production of hydrogen in silicone microreactors from water-ethanol mixtures
(Elsevier, 2017)
info:eu-repo/semantics/article,
Silicone microreactors containing microchannels of 500 μm width in a single or triple stack configuration have been manufactured, coated with an Au/TiO2 photocatalyst and tested for the photocatalytic production of hydrogen ...
Gold supported on CuOₓ/CeO₂ catalyst for the purification of hydrogen by the CO preferential oxidation reaction (PROX)
(Elsevier, 2014)
info:eu-repo/semantics/article,
Hydrogen produced from the conversion of hydrocarbons or alcohols contains variable amounts of CO that should be removed for some applications such as feeding low-temperature polymer electrolyte
membrane fuel cells (PEMFCs). ...
