NOVELTY - The production of high-compact hydrogen involves carrying out dynamic and static external uniform compression of hydrogen. The research is carried out by polylayer hydrogen intercalation between graphene layers containing carbon nanomaterial by providing pressure (due to energy of internal chemical reactions) to material and formation of high-compact intercalated hydrogen. The carbon nanomaterial is layered carbon nanomaterial comprising crystalline nano-fragments of graphene layers containing graphite nanofibers, carbon nanotubes, carbon nanocells and carbon fibrils. USE - Production of high-compact hydrogen. ADVANTAGE - The method enables safe and economical production of high-compact hydrogen. DETAILED DESCRIPTION - The production of high-compact hydrogen having density of 1 g/cm3 or less involves carrying out dynamic and static external uniform compression of hydrogen under pressure of 102 hPa. The research is carried out by polylayer hydrogen intercalation between graphene layers containing carbon nanomaterial comprising graphite nanofibers and carbon nanotubes by providing pressure (due to energy of internal chemical reactions) material and formation of high-compact intercalated hydrogen. The carbon nanomaterial is layered carbon nanomaterial comprising crystalline nano-fragments of graphene layers containing graphite nanofibers, carbon nanotubes, carbon nanocells and carbon fibrils. The preliminary purification of nanomaterial is carried out by annealing under inert gas atmosphere, and harmful impurities and oxide functional groups are removed, and the hydrogen sorption by nanomaterial is impeded or prevented. The carbon nanomaterial is formed on interfragment surfaces of section of layer of chemisorbed hydrogen e.g. atomic or ionized hydrogen which absorbs into nanomaterial, and hydrogenation is carried out at 1000K and 300 bar or less for 300 hours. The graphene inner surfaces are formed in nanofragment of carbon nanomaterial and a layer of chemisorbed hydrogen which enables predetermined cohesion weakening is formed between adjacent graphene layers of nanomaterial. The polylayer hydrogen intercalation is carried out by catalytic atomization of molecular hydrogen, thermal dissociation of molecular hydrogen on hot metal surfaces, high-frequency discharge treatment, hydrogen plasma treatment and/or electrochemical hydrogen ionization. The near and/or interfragment surfaces of section of carbon nanomaterial are hydrogenated at 1000K and 300 bar or less for 300 hours. The catalytic hydrogen atomization in interfragment sections of carbon nanomaterial is carried out by introducing nanoparticles of metal catalyst containing metal which dissociatively-absorbs hydrogen chosen from palladium, platinum, nickel, titanium, iron, cobalt, niobium, molybdenum, tantalum, tungsten, rhodium, ruthenium, osmium, iridium, lanthanum and/or magnesium. The hydrogenation of carbon nanomaterial is carried out using molecular hydrogen gas at 1000K and 300 bar or less for 300 hours.
