Abstract: A reactor system may comprise a moving bed reactor, a fluidized bed reactor, and a separation unit. The moving bed reactor may comprise catalyst material particles comprising a metal oxide support and a transition metal alloy, where the transition metal alloy comprises two transition metal elements. The moving bed reactor may comprise an inlet configured to receive a hydrocarbon and an outlet configured to provide hydrogen (H2) generated within the moving bed reactor. The fluidized bed reactor may be in fluid communication with the moving bed reactor and configured to receive the catalyst material particles and deposited carbon material from the moving bed reactor. The separation unit may be in fluid communication with an outlet of the fluidized bed reactor and configured to separate the catalyst material particles from carbon material and inert gas. The separation unit may be in fluid communication with the moving bed reactor.

Abstract: An exemplary reactor system may include a first reactor, a second reactor, a third reactor, and a fourth reactor. The first reactor may be in parallel with the second reactor and the third reactor. The second reactor and third reactor may be in series. The fourth reactor may be configured to receive reduced oxygen carriers from the other reactors, generate oxidized oxygen carriers, and provide the oxidized oxygen carriers back to the other reactors. Carbonaceous feedstock may be used within one or more reactors.
