Temperature Effect on the Rate of Hydrogen Desorption by Carbon Materials

The paper presents the theoretical foundations of carbon nanotubes, as well as the methods of the saturation of carbon materials containing nanotubes with hydrogen from the gaseous phase. The dependences of hydrogen storage concentration on the pressure (between 0 and 8 atmospheres) at the same temperature for adsorption (–30 degrees Celsius) and different temperatures for desorption have been obtained. Obviously, at 8 atmospheres the concentration of hydrogen storage varies with the change of the temperature. Particular attention was paid to the influence of the temperature on the rate of desorption.
