Abstract
Abstract Method in which a metal fuel in the form of molten droplets is brought into contact with water for reaction. The fuel comprises aluminum as a primary fuel component and at least one of lithium, magnesium, sodium, potassium and sodium-potassium alloy as an auxiliary fuel component and is used in the form of an alloy or a mixture of these fuel components. When used in the form of an alloy, the fuel is preheated to a molten state and injected into a reactor under high pressure, whereby the fuel is made into droplets and contacted with water vapor introduced into the reactor from another system. For use as a mixture, the fuel is made into a slurry the liquid phase of which consists singly of the auxiliary fuel component, and the slurry is injected into an atmosphere containing water vapor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
241 words
A method of producing a high pressure hydrogen which comprises the steps of: a. injecting into an essentially closed reactor vessel a fuel reactant composition consisting essentially of aluminum as a primary fuel component and at least one metal selected from the group consisting of an alkali metal and an alkaline earth metal alloyed or admixed therewith and serving as an auxiliary fuel component in said fuel reactant composition, and said fuel reactant composition being injected into the reactor through injection nozzles, each measuring 0.3 - 1 mm. in the orifice diameter, in the form of molten droplets and at least 20° C higher, but not more than 200°C higher, than the melting point of said fuel reactant composition, and said fuel reactant composition being introduced from a fuel container pressurized to 5 kg/cm 2 with argon gas, and the aluminum employed as starting material to form the fuel reactant composition being from 10-20 microns in size; b. separately injecting water, under pressure, at the same time into the reactor through nozzles each having nearly the same orifice diameter as the fuel injection nozzles to form water vapor in the reactor; c. vigorously reacting the reactant fuel composition with the water vapor in the reactor to produce a high temperature, high pressure hydrogen and so that at least 90% of the reactant fuel composition is reacted; d. removing the said high temperature, high pressure hydrogen through an exit port or nozzle.
