  • Publication number: 20220073345
    Abstract: The present disclosure relates to a low temperature method for the production of pure hydrogen using a methane rich stream as raw material, and to perform in-situ catalyst regeneration. The process involves the decomposition of methane into COx-free hydrogen in an electrochemical/chemical membrane/chemical reactor or chemical fluidised reactor. As the methane decomposition reaction progresses, carbon structures (whiskers) are accumulated at the catalyst surface leading eventually to its deactivation. The catalyst regeneration is achieved using a small fraction of the produced hydrogen to react with carbon formed at the catalyst surface provoking the carbon detachment, thus regenerating the catalyst. This is achieved either by chemical/electrochemical methanation of carbon at the catalyst interface with hydrogen/protons or by rising the temperature of the catalyst, ideally keeping the reactor temperature constant.

  • Patent number: 10629386
    Abstract: Solar cells use as substrates glass (23) coated with a transparent conductive layer (21), able to collect the electric power generated by the solar cell. This layer (21), normally a TCO, have limited conductivity, implying the use of current collector lines applied in a complex manner. The conductivity of the conductive layer (21) is increased by the application of a structure, in particular a grid, of thin conductive lines (22) inserted in grooves on the glass surface (23) or directly applied on this, followed by a TCO layer coating (21). This highly conductive grid (22) collects the electricity from the TCO layer (21) and directs it to the periphery of the cell. Both glass substrates are sealed by a process employing a precursor of glass surrounding the entire perimeter of the substrate. The glass precursor is heated to its melting point, by a laser, completely sealing the two substrates of the module.

  • Patent number: 8567110
    Abstract: The presently disclosed subject matter describes a new sealing process of a specific type of photovoltaic cells named dye-sensitized solar cells. Currently, the sealing of these cells is made by means of a polymer, which connects the two electrode substrates made of glass, isolating the cell's inner content from the outside. The glass-based sealing method has the advantage of enhancing the cell's lifetime. However, glass sealing should not lead to the heating of the whole cell, which may cause its degradation. The process here unveiled employs a string of a glass precursor, a powder or a paste, that bounds the cell's entire external perimeter. The glass precursor string is then heated to its melting point with a laser beam, allowing the two substrates of the cell to stick together.

  • Publication number: 20100047422
    Abstract: The present invention concerns a process for enriching the aroma profile of beverages, especially beer and wine, by means of extraction, using pervaporation, of aromas from the original beverage and subsequent addition of the extracted aromas to the beverage, after total or partial dealcoholization. The original beverage (1) is fed to the membrane separation module (4) wherein the permeate side (5) is under vacuum, provided by a vacuum pump (12). The feed contacts with the membrane surface and the aromas are selectively permeated to the permeate side of the membrane, where they suffer evaporation. The vapor permeate stream (5) is condensed (10) at an appropriate temperature, which can be cryogenic. After the aroma extraction, the beverage (6) is fed to a dealcoholization unit (14) for obtaining a non-alcoholic drink (15), however depleted in aroma compounds.

  • Publication number: 20090270665
    Abstract: The present invention discloses a device, which uses membranes, capable of separating olefins from paraffins. The device (1) considers an ultramicroporous ceramic membrane module, zeolite or silicate based, containing a fixed carrier of copper I or silver ions (#-complexant ions) inserted by ion exchange, or as a monolayer of CuCl, AgNO3, Cu or Ag+ (2). Olefins have higher diffusivity and affinity to the membrane than the remaining species, therefore the bicomponent permeation selectivity becomes reinforced when compared to the ideal permeation selectivity. The purification of olefins by removal of dienes and/or alkynes, is accomplished with a zeolite membrane functionalized with Ag+ and having a specific catalyst in the permeate side (4), e.g. palladium nanoparticulated, for catalyzing the hydrogenation of the permeating dienes and alkynes to the corresponding olefins, thus increasing the selectivity and the driving force of the separation.

  • Patent number: 7442236
    Abstract: The present invention concerns the application of adsorption gas separation technologies to anaesthesia equipment and falls within the technical domains of adsorption separation units and medical devices. The invention concerns a device and processes for recovering xenon from gas mixtures released from anaesthesia gas machines (1) using xenon as anaesthetic. The purged xenon is collected using a system which includes a shift valve (6), and then separated and purified (38-40). The recycled xenon is then pressurised (31) and reintroduced in the anaesthesia circuit (48) using a shift valve (12). The separation and purification process combines different adsorption separation/purification technologies. The device is external to the anaesthesia gas machine and is compatible with any standard anaesthesia circuit able of perform xenon anaesthesia.
