Item Fabrication of supported palladium alloy membranes using electroless plating techniques(Elsevier Ltd., 2015) Pacheco Tanaka, D. A.; Okazaki, J.; Llosa Tanco, M. A.; Suzuki, T. M.; TECNOLOGÍA DE MEMBRANAS E INTENSIFICACIÓN DE PROCESOSItem Fusion Exhaust Gas Separation with a Carbon Molecular Sieve (CMS) Membrane(2019-06-01) De Meis, D.; Serra, E.; Richetta, M.; Llosa Tanco, M. A.; Pacheco Tanaka, D. A.; TECNOLOGÍA DE MEMBRANAS E INTENSIFICACIÓN DE PROCESOSAbstract : The exhaust gas in the future Tokamak demonstration reactor (DEMO) consists of more than 80 % of unburned fuel gas (D and T) with the balance being He, plasma enhancement gases (PEGs), and impurities. In DEMO we plan to recover the fuel gas (D and T) and PEGs. The paper focuses on the removal of He from the fuel gas and PEGs from the fusion reactors. Hence, the aim of the research is to test potential technologies to achieve this goal. In this paper, a carbon molecular sieve (CMS) membrane supplied by Tecnalia (Spain) is tested to remove the He along with D and T whilst retaining the PEGs.Item Pore flow-through catalytic membrane reactor for steam methane reforming: characterization and performance(2022-07-12) Angulo, M.; Agirre, I.; Arratibel, A.; Llosa Tanco, M. A.; Pacheco Tanaka, D. A.; Barrio, V. L.; TECNOLOGÍA DE MEMBRANAS E INTENSIFICACIÓN DE PROCESOSA series of pore flow-through catalytic nonselective membrane reactors (PTCMRs) were studied for steam methane reforming (SMR) in the 500 to 900 °C temperature range under 10 barg pressure and a steam-to-carbon ratio of 5. The reactants flow through the pores of the membrane where they react on contact with the Pd nanoparticles. Various reactor configurations were prepared and tested with porous α-Al2O3-based ceramic tubes with one or more γ-Al2O3/YSZ layers on the external surface. The palladium content and dispersion affect the catalytic activity of the reactors and the results show that the efficiency of the reactions depends on the number of γ-Al2O3/YSZ layers.
