Abstract
A fuel system for a propulsion system includes a fuel deoxygenating device and a catalytic module containing catalytic materials. The fuel deoxygenating device removes dissolved oxygen from the fuel to prevent formation of insoluble materials that can potentially foul the catalyst and block desirable catalytic reactions that increase the usable cooling capacity of an endothermic fuel.
Claims20
A propulsion system comprising:
- an energy conversion device;
- and
- a fuel delivery system comprising a fuel deoxygenator for removing a portion of dissolved gases from a fuel and a catalyst receiving fuel from the fuel deoxygenator and initiating endothermic decomposition of the fuel.
A fuel delivery system for a propulsion system comprising:
- a fuel deoxygenator for removing a portion of dissolved gases from fuel;
- and
- a catalyst receiving fuel exiting said fuel deoxygenator and initiating endothermic decomposition of the said fuel.
