METHOD AND COMPOSITION FOR PRODUCTION OF HYDROGEN

Document Type and Number:

WIPO Patent Application WO2006072115

Kind Code:

A3

Abstract:

A method and composition for producing hydrogen by water split reaction, at near neutral pH conditions and without requiring preheating of the reactant materials. Metallic aluminum in particulate form is combined with a metal oxide initiator that raises the temperature of the reactant material upon exposure to water, to a level which initiates reaction of water with the aluminum to generate hydrogen, and a catalyst that creates progressive pitting of the metallic aluminum to prevent passivation. The metal oxide initiator may be an alkaline metal earth oxide, with calcium oxide being preferred. The catalyst may be a water soluble inorganic salt having an aggressive anion, such as the halides, sulfites, sulfates and nitrates of alkaline metals and alkaline earth metals, with sodium chloride being preferred. The metallic aluminum may be in the form of a milled particulate, and may be combined with the salt catalyst in a mechanical alloy. The reaction initiates upon adding normal tap water at ambient temperature, and is capable of generating hydrogen at low pressures or at elevated pressures of 7,000 psig or more. The reaction products can be recycled or disposed of safely without presenting hazards to the environment.
