  • the membrane element is first heated by passing a pulsed electric current through it at a certain frequency. Heating of the gas mixture (to increase the diffusion capacity of the gas) is not required, because in this system we have a large amount of superheated steam and the reactor cooling system 10. Due to the heating of the membrane element containing the catalyst with superheated steam, upon contact with the gas mixture, hydrogen molecules are split, and H atoms pass through the crystal lattice of the membrane element, followed by the formation (recombination) of hydrogen molecules. To prevent sticking of oxygen molecules and atoms on the inner working surface of the membrane filter, an ultrasonic wave is created inside the membrane filter chamber at the resonance frequency of the water molecule, which additionally creates an excited environment and significantly contributes to the intensification of the process.
  • the method of waste destruction with the device as described above is the following. From the moment the reactor enters the operating mode, thermodynamic equilibrium is instantly established in the reaction zone. Thus, it happens that the products of gaseous emission leave the reaction zone at the maximum combustion temperature. This is extremely important from the point of view of the subsequent generation of hydrogen and electricity. To create a highly efficient superadiabatic filtration reactor, it is necessary to create a highly effective thermal insulation of the reactor walls, in which case the heat loss through the reactor walls will be insignificant relative to the thermal power generated in the plasma-chemical reaction zone, heat losses through the reactor walls can be neglected. The removal of heat from the reactor occurs due to the forced flow of hot reaction products. There is no conductive heat removal from the ends of the reactor.
  • the thickness of the thermochemical reaction zone can be considered small compared to the total thickness of the heated layer including the gasification zone, so the reaction zone is a break in the fluidized bed with infinite rates of chemical reaction and heat transfer, limited by the upper boundary layer separating the fluidized bed and the gasification zone.
