Hydrogen is considered as a real alternative for improving the current energy scenario in near future and separation processes are crucial step economy of process both centralized distributed production systems. In this context, Pd-based composite membranes appear an attractive technology trying to reduce Pd thickness by modifying commercial supports, mainly formed metals fit properly conventional industrial devices. most cases, final calcination required hence, metallic support can be...
In this study, the optimal permeance ratio and layers distribution in multilayer membranes thin films which each layer obeys following real-power law: are determined for any positive real values of ni. Such an exponent has a physical meaning several cases, such as: diffusion-controlled permeation hydrogen metal i) under infinite-dilution conditions (n = 0.5), ii) higher-concentration ones (0.5 < n 1.5), iii) desorption-limited 1) same type membranes, Knudsen-type diffusional mechanism...
Olive mill wastewater (OMW) presents high environmental impact due to the fact of its elevated organic load and toxicity, especially in Mediterranean countries. Its valorization for simultaneous pollutants degradation green energy production is receiving great attention, mainly via steam reforming hydrogen generation. Following previous works, present research goes into detail about OMW valorization, particularly investigating first time potential benefits OMW–bioethanol mixtures...
The use of H2-selective membranes for ultra-pure H2 production has been assigned as an attractive technology, particularly those based on Pd-films deposited onto porous stainless-steel (PSS) supports. ability to incorporate thin with enough adherence any internal or external surfaces becomes essential minimize their complexity and cost while improving performance. modification original PSS substrates diverse intermediate layers, especially made ceria, is presented a promising alternative. In...
Different strategies to prepare H2-selective composite-membranes demonstrate promising performances, although the selection of optimum alternative must consider environmental and economic concerns. These aspects, scarce in available literature, are addressed here analyze convenience using diverse CeO2-based intermediate layers composite Pd-membranes recommend a maximum membrane length for scaling-up. The replacement raw dense-CeO2 by porous or Pd-doped particles layer clearly improves...
This work addresses the use of TiO2-based particles as an intermediate layer for reaching fully dense Pd-membranes by Electroless Pore-Plating long-time hydrogen separation. Two different layers formed raw and Pd-doped TiO2 were considered. The estimated Pd-thickness composite membrane was reduced in half when ceramic doped with Pd nuclei before their incorporation onto porous support vacuum-assisted dip-coating. real thickness top Pd-film even lower (around 3 μm), evidenced cross-section...
