The invention relates to the synthesis of urea from ammonia and carbon dioxide, wherein the hydrogen required for ammonia synthesis is obtained both by steam reforming of feed natural gas (grey hydrogen) and by electrolysis of water using electricity from renewable energy sources (green hydrogen). As the proportion of green hydrogen increases, the amount of carbon dioxide formed in the synthesis gas during steam reforming is no longer sufficient for the synthesis of urea. Therefore, flue gas, which is formed during the combustion of a fuel gas composed of fuel natural gas and combustion air and which also contains carbon dioxide, is additionally used. The oxygen formed during the electrolysis of water is introduced into the flue gas, and the modified flue gas is fed to a secondary reformer; and/or the fuel natural gas is combusted together with combustion air and the oxygen formed during electrolysis. Excess nitrogen is preferably separated from the synthesis gas before it is used for the synthesis of ammonia.

Resumen de: EP4818367A1
The development of more cost-effective and efficient proton exchange membrane (PEM) water electrolysis cells requires the use of thinner membranes with extended lifetimes and reduced gas crossover. The inventive approach to address these challenges involves the incorporation of radical scavengers to mitigate radical-induced ionomer degradation, along with gas recombination catalysts to promote the conversion of crossover hydrogen and oxygen to water inside the PEM. Each of the two catalyst types has its distinct chemical reaction characteristics, to which the design of the composite membrane is tailored through rational considerations. In various embodiments of the present invention, the positioning effects of Ce0.5Zr0.5O2 and Pt interlayers in composite membranes for their respective roles in radical scavenging and gas recombination were investigated. Results reveal that placing a radical scavenger interlayer near the cathode notably reduces the ionomer degradation rate, compared to its placement near the anode, evidenced by a 61% ± 7% reduction in fluoride release rate. This is likely due to reactive oxygen species in the cell being predominantly generated at the cathode, which is closer to the radical scavenger interlayer in the former case. The Ce content in cerium-zirconium oxide was further optimized using an ex-situ Fenton test, with Ce0.25Zr0.75O2 demonstrating the highest radical scavenging activity.

0001 A system and method are disclosed for the production of green hydrogen and oxygen from water using thermal decomposition driven by pulsed or continuous-spin detonation waves. In some embodiments, fresh water is converted into low-temperature steam and superheated beyond 3500°C using multi-stage shock-resonant compression within cooled gas-dynamic resonators, leading to dissociation of water into hydrogen and oxygen. In other embodiments, salt water is first desalinated by detonation-induced evaporation and fragmentation, producing steam and sea salt, after which the steam is thermally decomposed. A centrifugal vortex reactor is used to separate the resulting hydrogen and oxygen gases based on molecular weight. The system is capable of operating in a self-sustaining mode by recycling part of the generated gases for continued detonation. It is suitable for terrestrial and space-based applications, providing scalable, carbon-neutral hydrogen and oxygen production from fresh or salt water without the need for external electricity or fossil fuels.

The invention relates to catalytically coated anion exchange membranes and to the production thereof. The catalytically actively coated anion exchange membranes are used in electrochemical cells, especially for water electrolysis. The invention addresses the problem of providing a method for producing an electrocatalytically actively coated anion exchange membrane, the coating of which is porous and thus the electrocatalytically active centres located in the coating are easily accessible for the reactants. A basic concept of the method according to the invention consists in incorporating particulate inorganic material into the catalyst coating as a placeholder, solidifying the coating, and subsequently leaching the inorganic material out of the coating again. As a result of the leaching, the inorganic material is converted into a water-soluble product which can easily be washed out of the coating. Cavities (pores) remain at the points where the particulate inorganic material was previously located within the coating. Within the coating composition, the inorganic material therefore assumes the function of a structuring means which is lost in the course of the catalytically active coating.

Crossover through submicron thick SiO2 membranes can be mitigated by selectively depositing oxide, e.g., carbon-containing silicon oxide (SiOxCy) “nanoplugs” into the pinholes and cracks of the membranes. Defect-containing membranes are contacted with a deposition solution including hydrolysable precursors, e.g., metal alkoxides like tetraethyl orthosilicate (TEOS), and a nanoplug directing agent, e.g., tetramethylammonium bromide (TMAB). Current is applied to the defect-containing membranes in pulses, including a shorter “on” phase where current is applied and a longer “off phase” where current is not applied. The SiOxCy nanoplugs are deposited to the structural defects during the “on” phase. The longer “off phase” enables reactants to diffuse back to the structural defects for deposition of additional nanoplugs during the next “on” phase, as well as prevent deposition of SiOxCy on non-defective regions. Treatment of plugged SiO2 membranes reduced H2 permeation rates by 5-6 orders of magnitude compared to unmodified SiO2 and 1-2 orders of magnitude compared to Nafion-117 membranes.
