Hydrogen generation assemblies, hydrogen purification devices, and their components, and methods of manufacturing those assemblies, devices, and components are disclosed. In some embodiments, the devices may include an insulation base having insulating material and at least one passage that extends through the insulating material. In some embodiments, the at least one passage may be in fluid communication with a combustion region.

A thermochemical labyrinth reactor is disclosed. The reactor has a reoxidation zone and a reduction zone with electric heaters. A recuperation zone connects the reduction and reoxidation zones with first and second channels, the first channel adjoining the second channel, being separated by windows allowing an exchange of thermal radiation between channels while preventing gas exchange. The reactor also includes reactor plates composed of a reactive material, and a transit system running through the three zones, with the transit system configured to shuttle the plates between the reduction zone and the reoxidation zone, moving the plates along a circuit. The reactor also has a feedstock gas emitter to introduce a feedstock gas flowing opposite the movement of the plates. A gas extractor is configured to extract a product gas resulting from the feedstock gas being split by the oxidizing reactive material. All three zones are surrounded by an insulating housing.

A process for increasing the productivity of equilibrium-restricted reactions and for increasing the productivity of a target compound includes the steps of (a) providing a reaction mixture comprising reactants; (b) subjecting the reaction mixture to the equilibrium reaction in a reactor or sequence of reactors, to obtain a reactor outlet mixture comprising the target compound and at least one of the reactants; (c) regenerating the loaded sorbent obtained in step (e), by flushing the loaded sorbent with the reactor outlet mixture originating from step (b), to obtain regenerated sorbent and an effluent comprising desorbed product; (d) separating the effluent originating from step (c) into a product stream and a reactant stream; and (e) a sorption step to obtain a loaded sorbent and a depleted mixture.

The invention relates to a chemical reactor and reformer tubes for reforming a first feed stream comprising a hydrocarbon gas and steam. The chemical reactor comprises a shell with a heat source and one or more reformer tubes. The reformer tube is arranged to house catalyst material and is arranged to being heated by the heat source. The reformer tube comprises a first inlet for feeding said first feed stream into a first reforming reaction zone of the reformer tube, and a feed conduct arranged to allow a second feed stream into a second reforming reaction zone of the reformer tube. The second reforming reaction zone is positioned downstream of the first reforming reaction zone. The feed conduct is configured so that the second feed stream is only in contact with catalyst material in the second reforming reaction zone. The invention also relates to a process of producing CO rich synthesis gas at low S/C conditions.

Systems and methods are provided for improving the operation of groups of reverse flow reactors by operating reactors in a regeneration portion of the reaction cycle to have improved flue gas management. The flue gas from reactor(s) at a later portion of the regeneration step can be selectively used for recycle back to the reactors as a diluent/heat transport fluid. The flue gas from a reactor earlier in a regeneration step can be preferentially used as the gas vented from the system to maintain the desired volume of gas within the system. This results in preferential use of higher temperature flue gas for recycle and lower temperature flue gas for venting from the system. This improved use of flue gas within a reaction system including reverse flow reactors can allow for improved reaction performance while reducing or minimizing heat losses during the regeneration portion of the reaction cycle.

A method for producing hydrogen includes flowing a first gas along a bayonet flow path of a steam methane reformer (SMR) to produce a first product, including flowing the first gas through a foam disposed along the bayonet flow path; providing the first product produced in the SMR to an input of a water gas shift (WGS) reaction channel defined within a reaction tube of a WGS reactor; and flowing a second gas including the first product through the WGS reaction channel to produce a second product. Flowing the second gas includes flowing the second gas across a heat transfer material disposed in the WGS reaction channel to reduce the temperature of the flowing second gas; and flowing the second gas across a WGS catalyst disposed in the reaction channel.

Hydrogen generation assemblies, hydrogen purification devices, and their components, and methods of manufacturing those assemblies, devices, and components are disclosed.

In some embodiments, the at least one passage may be in fluid communication with a combustion region.

A reverse flow reactor (RFR) and process having a forward reaction feed cycle, a reverse reaction feed cycle, and a reverse regeneration cycle. The heat convected in the forward feed cycle matches the heat convected in the reverse flow cycles. Compared to an RFR without the reverse feed cycle, the three-cycle RPR substantially reduces the regeneration air flow rate, associated compression requirements, and the overall reactor volume, that are required.
