In a reactor for partial oxidation of feedstock employing a hot oxygen stream that is generated by a suitable burner, the same burner that generates and provides the hot oxygen stream in full-scale partial oxidation operation can be employed in the starting-up of the partial oxidation reactor by suitable control of the characteristics of the feed to the burner, or of the pressures.

Methane may be reformed through use of a solar reformer. Example methods of methane conversion through solar energy may include: supplying water and methane to a reaction chamber of a solar reformer unit; directing, using a solar reflector external to the reaction chamber, sunlight to one or more exterior solar absorbers of one or more solar absorbers; converting the sunlight into heat with the one or more solar absorbers; directing a portion of the heat converted by the one or more exterior solar absorbers to an interior of the reaction chamber using one or more light-porous pipes disposed within the reaction chamber; vaporizing at least a portion of the water to steam; and generating, within the reaction chamber, a reformate gas from the methane and the steam by a steam-methane reaction aided by one or more catalyst rods disposed within the reaction chamber.

A method for producing a synthetic fuel from hydrogen and carbon dioxide comprises extracting hydrogen molecules from hydrogen compounds in a hydrogen feedstock to produce a hydrogen-containing fluid stream; extracting carbon dioxide molecules from a dilute gaseous mixture in a carbon dioxide feedstock to produce a carbon dioxide containing fluid stream; and processing the hydrogen and carbon dioxide containing fluid streams to produce a synthetic fuel. At least some thermal energy and/or material used for at least one of the steps of extracting hydrogen molecules, extracting carbon dioxide molecules, and processing the hydrogen and carbon dioxide containing fluid streams is obtained from thermal energy and/or material produced by another one of the steps of extracting hydrogen molecules, extracting carbon dioxide molecules, and processing the hydrogen and carbon dioxide containing fluid streams.

A hydrogen generation system with controlled water distribution is disclosed. The system comprises a reaction chamber containing a hydrogen-producing fuel, a liquid distribution mechanism, and a control system. The liquid distribution mechanism includes a rotating arm with liquid injection ports that move vertically through the fuel chamber. This allows for precise and efficient liquid delivery to unreacted fuel, optimizing hydrogen production. A proprietary fuel blend utilizes chemicals that store significant amounts of hydrogen in a solid-state form. A feature of the device is the arm's controlled vertical movement, achieved through a screw mechanism that adjusts the arm's height as it rotates, creating a spiral liquid distribution pattern. The control system regulates liquid injection rates, arm rotation speed, and vertical movement to optimize hydrogen production based on demand. The system can also operate at low pressures and be scaled to different sizes in a safer, more efficient, on-demand manner.

A process for the production of hydrogen comprises: a first steam reforming step of a feedstock containing hydrocarbons to obtain a first synthesis gas; a first synthesis gas shift and cooling step on the first synthesis gas; a separation step for separating the first synthesis gas into a high concentration hydrogen stream and a tail gas stream; a second low pressure steam reforming step performed on the tail gas to obtain a second synthesis gas; a second synthesis gas shift and cooling step on the second synthesis gas; a CO2 removal step performed on the stream of hydrogen and carbon dioxide exiting the second synthesis gas shift and cooling step in order to separate a CO2 stream from a fuel grade hydrogen stream; a step of feeding at least a part of the fuel grade hydrogen stream to the first steam reforming step.
