METHOD OF PRODUCING HYDROGEN BY HYDROLYSIS OF SOLID REAGENT - ALUMINIUM IN REACTION VESSEL Russian patent published in 2015 - IPC C01B3/08 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing hydrogen by hydrolysis of a solid reagent - aluminium - in a reaction vessel and can be used to produce hydrogen in stand-alone power generation, primarily in power plants with electrochemical generators, such as fixed plants, on vehicles, and when repairing hydrogen-cooled electric generators and in chemical industry. Disclosed is a method of producing hydrogen by hydrolysis of aluminium in a reaction vessel filled with aqueous sodium hydroxide solution. The method of producing hydrogen is carried out in a continuous reactor by feeding aluminium in the form of an aqueous suspension. Before feeding into the reaction vessel, the aqueous suspension of aluminium is gelled (thickened). The gelling (thickening) additive used is modified polyacrylic acid or agar-agar.

EFFECT: invention increases cost effectiveness of producing hydrogen and improves the quality of hydrolysis and control of the hydrogen production process.
