Solution production devices, systems, and methods. The system includes a base portion configured to receive a vessel containing a liquid. Upon the base portion receiving the vessel, liquid is transferred from the vessel and into the base portion where it undergoes an electrochemical reaction to produce a cleaning solution. The cleaning solution is then circulated back into the vessel.

A process for preparing synthetic hydrocarbons from a biomass feedstock is provided. The process involves electrolyzing water in an electrolyzer to produce oxygen and hydrogen, using the generated oxygen to gasify a biomass feedstock under partial oxidation reaction conditions to generate a hydrogen lean syngas, adding at least a portion of the generated hydrogen to the hydrogen lean syngas to formulate hydrogen rich syngas, which is reacted a Fischer Tropsch (FT) reactor to produce the synthetic hydrocarbons and water. At least a portion of the water produced in the FT reaction is recycled for use in the electrolysis step, and optionally using heat generated from the FT reaction to dry the biomass feedstock.

The invention provides a method of reducing dinitrogen to produce at least one haloamine compound, the method comprising: contacting a cathode comprising a dinitrogen-activating electrocatalytic composition with an electrolyte; providing dinitrogen, a reducible source of halogen and a source of hydrogen for reaction at the cathode; and applying a potential at the cathode sufficient to reduce the dinitrogen on the dinitrogen-activating electrocatalytic composition in the presence of the reducible source of halogen and the source of hydrogen, thereby producing at least one haloamine compound.

Matrix cells are used to improve the regeneration capacity of an electrolyzer system. The electrolyte is electrolyzed in the matrix cell. Gas (predominantly product gas) which has unwantedly accessed the electrolyte space is transported off from the electrolyte space into the gas space envisioned therefor by a degassing device. Additional measures such as ultrasonic transducers and field electrodes may realize electrolyte flow and improved transporting-off of gas.

Energy efficiency and/or operational stability of a multistage compression system comprising a plurality (N) of centrifugal compressors that is compressing a gas feed having a variable flow rate is improved by adjusting reversibly the load on each compressor in response to changes in the flow rate of the gas feed using a main recycle system to enable operation of the centrifugal compressors at turndown capacity during periods when the flow rate is below total turndown capacity for all of the compressors, and if necessary, using the local recycle systems in order to avoid activation of anti-surge control, and switching one or more centrifugal compressors into low power mode or shutdown mode as required.

The invention relates to a method for producing isocyanates and optionally polyurethanes by at least: synthesising (1) phosgene (20) from carbon monoxide (21) and chlorine (22); reacting (2) phosgene (20) with diamines (23) to form diisocyanates (24) and hydrogen chloride (25); providing a carbon dioxide gas flow (31); and cleaning (4) the carbon dioxide gas flow (31) of additional components, wherein the carbon dioxide is converted by means of an RWGS reaction (6) to form carbon monoxide (21) and hydrogen (29), which are used as raw materials for the polyurethane production, as well as optionally reacting (3) the diisocyanates (24) with polyether polyol (35a) and/or polyester polyol (35b) to form polyurethanes (37).

An electrolytic cell includes a liquid metal cathode, an anode, and a molten salt electrolyte in contact with the liquid metal cathode and the anode. The molten salt electrolyte includes carbonate ions, and the electrolytic cell is configured to reduce the carbonate ions at the surface of the cathode or in the vicinity of the cathode to yield a carbon material and oxide ions. Producing a carbon material in the electrolytic cell includes providing carbonate ions to the electrolytic cell, reducing the carbonate ions at the liquid metal cathode to yield the carbon material, and removing the carbon material from the electrolytic cell.

A containerized system for producing anhydrous ammonia from air, water and a power source, includes a containerized hydrogen production unit that produces hydrogen gas from a water source by low temperature electrolyser, high temperature electrolyser, battolyser or by other methods; a containerized nitrogen production unit comprising an onboard air compression and storage unit that produces and stores pressurized air, a pressure swing adsorption process or other methods that use regenerative molecule that does not need any maintenance, which intakes compressed air and produces nitrogen gas through a series of adsorption and desorption processes, or other such methods of producing nitrogen from air; a containerized ammonia production unit comprising a gas booster that increases the pressure of a mixture of the hydrogen gas and the nitrogen gas using the pressurized air; a multi-reactor assembly joint in series or in parallel; and a recycle loop that separates the ammonia from unreacted gases.
