METHOD OF ACTIVATING ALUMINIUM FOR PRODUCING HYDROGEN Russian patent published in 2017 - IPC C01B3/08 

FIELD: chemistry.

SUBSTANCE: invention relates to production of hydrogen as a result of chemical reaction components hydro-reacting composition, more specifically to a method of activating aluminium for hydrogen generation, and can be used in designing hydrogen cartridges for small-size power sources on fuel elements. Method of activating aluminium for hydrogen production includes preparation of a mixture of components of indium, tin and gallium, preferably, at a ratio of 20:20:60 wt%, heating mixture until obtaining an eutectic alloy, which is then mixed at normal conditions in an inert atmosphere with powdered aluminium and abrasive substance with particle size 0.5-1.5 mm, mainly, from a group of sodium chloride or aluminium oxide, then mixture is subjected to mechanochemical treatment in an inert atmosphere at temperature 20-80°C for 5-20 minutes.

EFFECT: invention allows more complete oxidation of activated aluminium with low content of gallium and indium in hydro-reacting composition, increases rate of hydrogen generation and providing possibility of its adjustment, as well as higher profitability aluminium activation technologies.
