A gas separation method includes supplying a mixed gas to a zeolite membrane complex and permeating a high permeability gas through the zeolite membrane complex to separate the high permeability gas from other gases. The mixed gas includes a high permeability gas and a trace gas that is lower in concentration than the high permeability gas. The trace gas contains an organic substance whose molar concentration in the mixed gas is higher than or equal to 1.0 mol %. The adsorption equilibrium constant of the organic substance on the zeolite membrane is less than 150 times the adsorption equilibrium constant of the high permeability gas.

A method for decreasing the SFFC of a steam reforming plant, including establishing a base operating mode. Then modifying the base operating mode by introducing the shift gas stream into a solvent based, non-cryogenic separator prior to introduction into the pressure swing adsorption and introducing the compressed hydrogen depleted off-gas stream in a membrane separation unit, wherein the membrane is configured to produce the hydrogen enriched permeate stream at a suitable pressure to allow the hydrogen enriched permeate stream to be combined with carbon dioxide lean shift gas stream, prior to introduction into the pressure swing adsorption unit without requiring additional compression. Thereby establishing a modified operating mode. Wherein said pressure swing adsorption unit has a modified overall hydrogen recovery. Wherein said modified operating mode has a modified hydrogen production, a modified hydrogen production unit firing duty, a modified SCO2e, and a modified SFFC.

A plant and a method for the production of hydrogen and bicarbonate. The plant includes a gasifier, a reformer, a direct contact exchanger and an apparatus for the production of bicarbonate. The plant is suitable for receiving fuel, oxygen, water, carbonate, brine at the inlet and for producing hydrogen, bicarbonate and calcium chloride at the outlet. The plant uses a self-cleaning direct contact heat exchanger to cool the syngas downstream of the reformer and to produce the superheated steam that feeds the gasifier: this heat exchanger allows the production of hydrogen at low costs and in modular plants.

A system for disassociating molecules of a gas based on RF power. Characteristics of the RF power can be tuned to increase disassociation efficiency. The system can include a disassociation chamber configured to enclose a volume of a gas and a radio frequency (RF) power source configured to provide RF power to the disassociation chamber. The RF power source can include a radio-frequency generator configured to generate an electromagnetic (EM) radiation having a frequency between about 20 MHz and about 10 THz, a radio-frequency amplifier configured to amplify the generated EM radiation, and an output channel to direct the amplified EM radiation towards the volume of gas.

A system may include a chamber with a main sub-chamber and a first porous membrane separating a first sub-chamber from the main sub-chamber. The system may include a fluid in the chamber and an input directing inflow into main sub-chamber proximate an entry end of the chamber. The system may include a first output permitting outflow from the first sub-chamber proximate an exit end of the chamber wherein a molecule entering at the entry end must traverse a length of the chamber to exit at the exit end.

A hydrocarbon reclamator consists of a closed chamber having an exhaust inlet port, a hydrogen inlet port, and a hydrocarbon outlet port. A magnetic flux is generated at the base of the closed chamber and a rotor is suspended by the magnetic flux within the closed chamber. The rotor is formed as a Tesla turbine having axially spaced discs concentrically mounted on a central shaft, a catalyst is formed on surfaces of the discs, and flow holes are formed through the discs. Venturi forces direct gas to release kinetic energy against the discs, so that hydrogen entering the chamber combines with carbon entering the chamber to form a hydrocarbon that exits the chamber via the hydrocarbon outlet port.

An ink for three dimensional printing a ceramic material includes metal oxide nanoparticles and a polymer resin, where a concentration of the metal oxide nanoparticles is at least about 50 wt % of a total mass of the ink. A method of forming a porous ceramic material includes obtaining an ink, where the ink comprises a mixture of metal oxide nanoparticles and a polymer, forming a body from the ink, curing the formed body, heating the formed body for removing the polymer and for forming a porous ceramic material from the metal oxide nanoparticles. The forming the body includes an additive manufacturing process with the ink.

A carbon dioxide reduction system 1 comprises a transport path 4 that transports carbon dioxide and a reduction apparatus 5 that reduces heated carbon dioxide introduced through the transport path 4, wherein the carbon dioxide is heated in the transport path 4 by at least one of recycled energy and exhaust heat.
