    摘要： An ammonia production system includes a steam generation device configured to produce steam and an electrolyzer cell configured to produce hydrogen feedstock gas from the steam. A hydrogen combustor receives the hydrogen feedstock gas from the electrolyzer cell and combusts the hydrogen feedstock gas and produce heat and electricity. A combustion thermal conduit provides heat transfer between the hydrogen combustor and the steam generation device. An electrical generator is connected to the hydrogen combustor and configured to generate electricity.

    摘要： A process and system for synthesis of ammonia includes an electrochemical main cell and an electrochemical preliminary cell upstream of the main cell. A voltage is applied between the anode and cathode of the preliminary cell and the main cell. The anodic half-cell of the preliminary cell is supplied with water, and the cathodic half-cell of the preliminary cell with nitrogen and oxygen. Oxygen is in the anodic half-cell of the preliminary cell, and nitrogen and water are in the cathodic half-cell of the preliminary cell. The anodic half-cell of the main cell is supplied with water, and the cathodic half-cell of the main cell with nitrogen that has been obtained in the cathodic half-cell of the preliminary cell. Oxygen is in the anodic half-cell of the main cell, and ammonia in the cathodic half-cell of the main cell.

    摘要： Systems and methods for electrochemical ammonia synthesis comprise electrolytes which have greater efficiency than water, thus leading to cost reductions; and/or cathode catalysts which have lower costs and higher efficiencies in comparison to the iron/nickel catalysts noted above. The electrolyte may be composed primarily of a combination of non-aqueous hydrogen bond donors and acceptors, with high nitrogen solubility and high conductivity. The cathode catalyst may be composed of either a manganese-doped oxide or carbonate material or a two-dimensional carbide or nitride material.
