Catalyst Screening for Oxidative Coupling of Methane Integrated in Membrane Reactors

García-Fayos, Julio; Lobera González, Maria Pilar; Balaguer Ramirez, Maria; Serra Alfaro, José Manuel (Frontiers Media SA, 2018)

[EN] Increased availability of methane from shale gas and stranded gas deposits in the recent years may facilitate the production of ethylene by means of potentially more competitive routes than the state-of-the-art steam ...
Controlling the stress state of La1-xSrxCoyFe1 (-) O-y(3-delta) oxygen transport membranes on porous metallic supports deposited by plasma spray-physical vapor process

Marcano, Diana; Mauer, Georg; Sohn, Y. J.; Vaßen, Robert; García-Fayos, Julio; Serra Alfaro, José Manuel (Elsevier, 2016-04-01)

[EN] La0.58Sr0.4Co0.2Fe0.8O3-delta (LSCF), deposited on a metallic porous support by plasma spray -physical vapor deposition (PS-PVD) is a promising candidate for oxygen -permeation membranes. However, after O-2 permeation ...
Fast Oxygen Separation Through SO2- and CO2-Stable Dual-Phase Membrane Based on NiFe2O4-Ce0.8Tb0.2O2-delta

Balaguer Ramírez, María; García Fayos, Julio; Solis Díaz, Cecilia; Serra Alfaro, José Manuel (American Chemical Society, 2013-12-24)

Composite membranes with enhanced oxygen permeability and unprecedented stability in oxyfuel-like gas environments are reported. Specifically, 60 vol% NiFe2O4 - 40 vol% Ce0.8Tb0.2O2-delta (NFO-CTO) composite has been ...
Fluid Dynamic Modeling of Oxygen Permeation through Mixed Ionic-Electronic Conducting Membranes

Gozálvez-Zafrilla, José M.; Santafé Moros, María Asunción; Escolástico Rozalén, Sonia; Serra Alfaro, José Manuel (ELSEVIER SCIENCE BV, 2011-08-15)

[EN] The oxygen transport in a lab-scale experimental set-up for permeation testing of oxygen transport membranes has been modeled using computational fluid dynamics using Finite Element Analysis. The modeling considered ...
Improving the performance of oxygen transport membranes in simulated oxy-fuel power plant conditions by catalytic surface enhancement

Pirou, Stéven; García-Fayos, Julio; Balaguer Ramirez, Maria; Kiebach, Ragnar; Serra Alfaro, José Manuel (Elsevier, 2019-06-15)

[EN] The stability of dual-phase oxygen transport membranes consisting of 70 vol% (Y2O3)(0.01)(Sc2O3)(0.10)(ZrO2)(0.89) and 30 vol% MnCo2O4 (10Sc1YSZ-MCO (70-30 vol%)) was investigated in simulated oxy-fuel power plant ...
Oxygen transport membranes in a biomass/coal combined strategy for reducing CO2 emissions: Permeation study of selected membranes under different CO2-rich atmospheres

García Fayos, Julio; Vert Belenguer, Vicente Bernardo; Balaguer Ramírez, María; Solis Díaz, Cecilia; Gaudillere, Cyril Christian; Serra Alfaro, José Manuel (Elsevier, 2015-10-15)

[EN] This contribution introduces how the integration of biomass as fuel in power plants would balance CO2 emissions and the related role of oxygen transport membranes (OTM) on it. CO2 capture techniques could be introduced ...
Ultrahigh oxygen permeation flux through supported Ba0.5Sr0.5Co0.8Fe0.2O3-delta membranes

Baumann, S.; Serra Alfaro, José Manuel; Lobera González, Maria Pilar; Escolástico Rozalén, Sonia; Schulze-Kueppers, F.; Meulenberg, W. A. (Elsevier, 2011-07-15)

[EN] Oxygen transport membranes made of Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) were manufactured by tape casting and co-firing. The disk-shaped membranes consisted of a top gastight layer (70 mu m thick) and a porous substrate ...
