    Abstract: A reactor for performing equilibrium-reduced reactions, includes a tubular reactor housing in which a first zone is arranged, through which a liquid absorbent flows, and which extends in the longitudinal direction of the tube. Aa second zone is arranged for receiving a catalyst material and also extends in the longitudinal direction of the tube. The first zone and the second zone are separated by a gas-permeable separation zone. The separation zone has a mechanically self-supporting structure and the aspect ratio of the tubular reactor housing along a reaction zone is greater than 6.

    Abstract: A method for operating a reactor facility for equilibrium-limited reactions, includes: converting starting materials to a product in a reaction chamber under a pressure p1, wherein an absorbent is loaded with the product and absorbs starting materials; discharging the loaded absorbent from the reaction chamber; lowering the pressure of the absorbent to a pressure p2 which is lower than pressure p1 and the product and starting materials are discharged in the gaseous state from the liquid absorbent; separating the gaseous products by condensation from the gaseous starting materials at the same time as a pressure p3 higher than pressure p1 is applied to the liquid absorbent, under pressure p3 into a liquid jet gas compressor in which the gaseous starting materials separated from the products are aspirated and dissolved in the liquid absorbent; and then introduced under pressure p4, which is lower than pressure p3, into the reaction chamber.

    Abstract: Various embodiments include a process for converting a starting material mixture comprising carbon dioxide and hydrogen into methanol and water. The method may include: providing a catalyst to a reactor; feeding carbon dioxide and hydrogen into the reactor, at a first pressure and a first temperature; feeding a first liquid component into the reactor at a second temperature lower than the first temperature; converting the carbon dioxide and hydrogen into methanol and water; removing the methanol from a gas phase in at least one liquid phase comprising the first component and the water; and discharging a first liquid material stream comprising the first component, methanol, and water from the reactor. At the first temperature and the first pressure the methanol is in a gaseous state and the first component and the water are in a liquid state.

    Abstract: An electrolyser arrangement with at least one electrolytic cell, having two electrodes, namely an anode and a cathode, each of the two electrodes being in contact with an electrode compartment for filling with a liquid electrolyte, the two electrode compartments being separated by a membrane and a conveying device being provided, one for each of the two electrodes, for conveying the electrolyte in each case in a circuit, a cathode circuit and an anode circuit, through the electrode compartment via at least one collection vessel per circuit and back into the electrode chamber. A device is provided outside the electrolytic cell, for conveying an auxiliary volume flow between the cathode circuit and the anode circuit.

    Abstract: Various embodiments include a CO2 electrolyzer comprising: a gas space adjoining a cathode comprising a gas diffusion electrode adjoining a cathode space; an anode in an anode space; a membrane separating the cathode space from the anode space; a feed apparatus feeding reactant gas into the gas space; a mixing vessel for at least partial joint accommodation of the anolyte and the catholyte; and a connection line between the gas separating region and the gas space. The mixing vessel includes a gas separating region closed off with respect to a surrounding atmosphere. The cathode space accommodates a catholyte and the anode space accommodates an anolyte.
