Creation of the closed circuit of Al usage to get H, Н2О pair, nano-Al2О3 or nano-Al(ОН)3 doped by allotropes C.

Obtaining clear Н from Н2О significantly cheaper per Н2О electrolysis together with Н2О steam of adjustable temperature and pressure. It is the building owners, multi-apartment buildings, chemical, metallurgical and vehicle manufacturing industries, vessel building, rail transport, producers of fuel from atmospheric СО2.

The production of an equal amount of Н from metal Al and Н2О in a hydrodynamic cavitator consumes about 10 times less electrical energy than during the electrolysis of Н2О taking into account the energy for renewing Al from Al2О3. At the same time, high-temperature Н2О vapour is produced. Using this technology, the energy produced by wind and sun can be used in a much more efficient way. Oil and gas use in its current form will be economically and environmentally inappropriate. Energy will be stored in Al and Н2О and used for its intended purpose at exactly the time and place when it is needed in the necessary amount.

Heating in the EU uses 40% of the natural gas. The method proposed makes it possible to obtain heat and Н instead of natural gas.

The resulting mixture of H with Н2О vapour of high pressure and temperature can be used in the reaction with СО2 taken from the atmosphere to produce a particularly clean liquid fuel.

Together with H and heat, one can produce allotropes C doped with Al2О3, or Al (OH)3 of nanoscale level.

This method of producing H will allow to abandon using coke in the metallurgical industry.

The chemical industry requires this technology as well.

On ships, locomotives, trucks one can add a hydrogen-vapour mixture directly with the air in internal combustion engines, this will significantly reduce the amount of fuel consumed and increase the efficiency of its use with a decrease in СО2 emissions.

It is a new technology to get Н2 and Н2О vapour from the metal Al and H2O in a hydrodynamic cavitator. A similar result was obtained in vitro by the reaction of nano-Al + H2O with self-destructing Al and active heat and Н2 release. The temperature in the middle of the Al particles was significantly higher than their environment had.  This effect is explained by the presence of a large number of atoms on the surface of nanoparticles compared to their number in the volume. The heat released during the reaction is accumulated in the metal component of the nanoparticles, while the formation and accumulation of H2 oxide - metal lobes on the shell occurs at a high rate with the rupture of the oxide shell. The reaction byproduct is nano Al2O3 or Al (OH)3. In order to achieve an analogous result with an ordinary aluminum powder, a technology and a hydrodynamic cavitation device has been developed and patented, in which a reaction similar to nano-Al takes place between Н2О and conventional Al powder of micrometer size and possibly millimeter size at room temperature and atmospheric pressure. This is due to the fact that in the entire volume of the hydrodynamic cavitator reactor, cavitation bubbles are constantly formed in a suspension of Н2О with Al and are instantly destroyed, while thermal energy and high pressure are released directly near the Al particles, which leads to the grinding of micro – sized Al particles to their nanoscale level with the destruction of the oxide film, the hit of Н2О on pure Al, which in turn leads to a thermal chemical reaction between Н2О and Al, self-heating of the suspension with active release of a vapour-hydrogen mixture. In this case, 100% of Al reacts with Н2О. 1 mole of Al + 0.11 liters of Н2О = 33.6 liters of H. In the experimental part at a consumption of 0.3 kW the hydrodynamic cavitator used 0.5 kg of Al and 3.3 liters of Н2О. After 20 minutes of processing about, 13,43  MJ of heat energy and 670 liters of H were obtained.
