METHOD OF PRODUCING HIGHLY COMPACT HYDROGEN Russian patent published in 2013 - IPC C01B31/02 C01B3/00 B01J20/20 H01M8/22 B82B3/00 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in motorcar, chemical, electronic and electrochemical industry, as well as hydrogen power engineering. First, nanoparticles of a metal catalyst - Pd, Pt, Ni, Ti, Fe, Co, Nb, Mo, Ta, W, Rh, Ru, Os, Ir, La, Mg and/or alloys thereof are placed in inter-fragment regions of carbon nanomaterial - graphite nanofibres or carbon nanotubes. The carbon nanomaterial is then cleaned from attached oxide-type functional groups by burning in an inert gas at 773 K. A layer of chemisorbed hydrogen with thermal desorption activation energy of about 1.2 eV is then formed on the inter-fragment surfaces and a layer of chemisorbed hydrogen with thermal desorption activation energy of about 2.5 eV is formed on graphene inner surfaces by holding the carbon nanomaterial in a current of gaseous molecular hydrogen at temperature of 773 K. Final hydrogenation of the carbon nanomaterial is carried out in a container at pressure, temperature and time of not more than 300 bar, 1000 K and 300 h, respectively, until obtaining 10 wt % or more of highly compact hydrogen with density in the order of 1 g/cm³ which is intercalated in the carbon nanomaterial.

EFFECT: invention reduces the pressure and temperature when producing highly compact hydrogen, enables to use simple, available and low power consumption equipment, and provides prolonged storage of hydrogen at room temperature.
