Abstract:
Reactor/separator elements for performing the generation and/or separation of hydrogen gas with improved efficiency have a central core and a separation layer that, in combination, define at least one spiral gas flow channel extending from one end of the central core to the opposite end of the central core. In use, the reactor/separator element may be placed in a housing which constrains gas on the outside of the reactor/separator element into the spiral channel defined by the outside of the separation layer.

Abstract:
The invention relates to a method for producing ammonia by reacting N2 with H2 to produce a low-temperature plasma discharge. Said gas mixture, in which the low temperature plasma discharge is produced, can also contain a diluted inert gas and/or admixtures favouring the plasma discharge. Also, the reaction can take place in the presence of a catalyst.

Abstract:
An ammonia production process is disclosed. The process uses gasification of biomass waste and the like to produce syngas which, using an integrated system including using nitrogen enriched air and a porous coated catalyst, produces ammonia in a plasma reactor. The ammonia is finally recovered using sulphonated PolyHIPE Polymer which can be used as a fertilizer after neutralisation.
Abstract:
A method for producing ammonia comprises introducing N 2 and H 2 into a non-thermal plasma in the presence of a catalyst. The catalyst is effective to promote the dissociation of N 2 and H 2 which is used to form ammonia.
Abstract:
With this method and installation for producing ammonia, activation of nitrogen in the presence of hydrogen is achieved by means of the electrical discharge of a capacitor and the ammonia thus obtained is dissolved in the water which is present at the same time in the installation in an amount depending on the partial pressure, solubility and temperature of the reactants, and then spontaneously withdrawn from the chemical equilibrium, which leads to a steady production of ammonia. Ammonia is extracted by means of temperature modification of the ammonia solution produced by the installation, water is recirculated and ammonia obtained by separation is used for another purpose.
Abstract:
A process and system for electrolytic production ammonia. The process comprises feeding gaseous nitrogen to an electrolytic cell, where it comes in contact with a cathode electrode surface, wherein said surface has a catalyst surface comprising a nitride catalyst, said electrolytic cell comprising a proton donor,and running a current through said electrolytic cell, whereby nitrogen reacts with protons to form ammonia. The process and system of the invention uses an electrochemical cell with a cathode surface having a catalytic surface which is preferably charged with one or more of Vanadium nitride, Chromium nitride,Zirconium nitride, Niobium nitride, Iron nitride or Osmium nitride.
