COMPRESSED HYDROGEN PRODUCING METHOD AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC C01B3/08 F17C5/06 B01J7/02 

FIELD: chemistry; power engineering.

SUBSTANCE: invention relates to hydrogen power engineering, namely to technology and equipment for production of hydrogen and filling of vessels to required pressure for use as autonomous mobile plants for generation of hydrogen under high pressure with its subsequent filling into cylinders, intended for supply of fuel elements, providing operation of unmanned aerial vehicles, telecommunication equipment, computer equipment and other independent objects of power consumption. Method of producing compressed hydrogen involves chemical reaction of a hydrogen-generating material with a liquid reagent in reactor 1 with hydrogen evolution and filling it with filled balloon 12, wherein hydrogen generating material is magnesium, magnesium alloys or magnesium hydride, liquid reagent is aqueous acid solution, selected from the group: citric, acetic, hydrochloric, sulphuric, liquid reagent is preliminarily placed in separate tank 6 connected to reactor 1 by tube 3 with tap 4 separating reservoir 6 from reactor 1, displacing air from free volume of reservoir 6, hydrogen monitoring and purification system associated with reservoir 6 and refuelling balloon 12 or reactor 1, opening valve 4 separating said reservoir 6 with liquid reagent from reactor 1, and obtained hydrogen through gas outlet tube 16 is directed into reservoir 6 with liquid reagent, then into control and cleaning system, after which is collected in one or several successively filled to required pressure cylinders 12. Method is implemented in device including reactor 1, filled balloon 12, separate reservoir 6 for liquid reagent; doser-metering device 2 equipped with tube 14 for supply of liquid reagent directly to hydrogen-generating material and gas-venting tube 16, wherein pipe 3 for connection of reactor 1 and tank 6 with valve 4 for separation thereof is passed through metering nozzle 2. Nozzle 7 for connection of reservoir 6 and gas outlet tube 16 with control system and purification of evolved hydrogen containing pressure sensor 10, safety valve 9, filter elements 11; overpressure relief system comprising tube 18, safety valve 19 and valve 20, wherein the liquid reagent supply pipe 14 is equipped with a filter and is installed so that its outlet hole is located in the hydrogen generating material zone, the gas outlet pipe 16 is equipped with a filter, tap 17 and is located between nozzle-proportioner 2 and nozzle 7 for connection of reservoir 6 and gas discharge tube 16 with purification system of released hydrogen 10, 9, 11.

EFFECT: disclosed method of producing compressed hydrogen, comprising conducting a chemical reaction of a hydrogen-generating material with a liquid reagent in a closed volume, carried out in the disclosed device, having mobility and simple detachable structure and functioning without using additional power sources, makes it possible to obtain hydrogen in field conditions and to fill it with one or several successively filled cylinders to the required pressure.
