Abstract: A method for startup of a catalytic oxidation unit includes flowing air from an air source into the catalytic oxidation unit, recycling air from an outlet of the catalytic oxidation unit to an inlet of the catalytic oxidation unit through a recycle duct, and flowing a fuel from a fuel source into the catalytic oxidation to cause a catalytic reaction.

Abstract: Fuel tank inerting systems are provided. The systems include a fuel tank, an air source arranged to supply air into a reactive flow path, a catalytic reactor having a plurality of sub-reactors along the flow path, and a heat exchanger. The sub-reactors are arranged relative to the heat exchanger such that the flow path passes through at least a portion of the heat exchanger between two sub-reactors along the flow path. At least one fuel injector is arranged relative to at least one sub-reactor. The fuel injector is configured to inject fuel into the flow path at at least one of upstream of and in the respective at least one sub-reactor to generate a fuel-air mixture. A fuel tank ullage supply line fluidly connects the flow path to the fuel tank to supply an inert gas to a ullage of the fuel tank.
