The present disclosure relates to systems and methods useful for power production. In particular, a power production cycle utilizing CO.sub.2 as a working fluid may be configured for simultaneous hydrogen production. Beneficially, substantially all carbon arising from combustion in power production and hydrogen production is captured in the form of carbon dioxide. Further, produced hydrogen (optionally mixed with nitrogen received from an air separation unit) can be input as fuel in a gas turbine combined cycle unit for additional power production therein without any atmospheric CO.sub.2 discharge.

A processing facility is provided that includes a feedstock separation system configured to separate a feed stream into a lights stream and a heavies stream, a hydrogen production system configured to produce hydrogen and carbon dioxide from the lights stream, and a carbon dioxide conversion system configured to produce synthetic hydrocarbons or the carbon dioxide. The processing facility also includes a hydroprocessing system configured to process the heavies stream, and a hydroprocessor separation system configured to separate a hydroprocessing system effluent into a separator tops stream and a separator bottoms stream, wherein the separator bottoms stream is fed to the hydrogen production system.

A method and apparatus for generation of fluorine gas (F2) in situ at the point of use is provided. The portable fluorine generator includes a dilution system disposed within a housing and operable to mix a feed gas comprising fluorine with an inert gas. The portable fluorine generator further includes a plasma reactor unit disposed within the housing and operable to separate fluorine (F2) from the feed gas comprising fluorine.

A flow reactor system for providing on-demand H.sub.2 evolution at pressure from a liquid organic hydrogen carrier and/or blends thereof includes a reactor that includes a reaction vessel having an inlet and outlet. The inlet is configured to introduce reactants into the reaction vessel, and the outlet is configured to release reaction products. The reaction vessel is configured to hold therein a catalyst system capable of catalyzing the evolution of molecular hydrogen from a liquid organic hydrogen carrier. Advantageously, the reaction vessel is configured to operate at pressures greater than or equal to 50 psig (e.g., from about 50 psig to about 10500 psig. The flow reactor system also includes a source of preheated liquid organic hydrogen carrier in fluid communication with the reactor and a purification system in fluid communication with the outlet that provides purified molecular hydrogen gas for on-demand applications.

A fuel tank inerting system includes a primary catalytic reactor comprising an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from the fuel tank and air from an air source that are mixed to form a combined flow, and to react the combined flow along the reactive flow path to generate an inert gas. The system also includes an input sensor that measures a property of the combined flow before it enters the primary catalytic reactor and an output sensor that measures the property of the combined flow after it exits the primary catalytic reactor.
