THERMODYNAMIC AND TECHNOLOGICAL ASPECTS OF METAL HYDRIDE ACTIVATION OF HYDROGEN

Abstract

The interest in metal hydride activation is caused by the possible use of energy accumulating properties of the active forms of hydrogen while realizing the processes in energy-transducing devices as well as the reactions of heterogeneous catalysis and the catalytic methods of new hydrides and hydrogenous substances synthesis. On the basis of the thermodynamic analysis the quantitative estimation of superfluous energy has been made. This energy under certain conditions can be realized in the form of nonequilibrium concentration of particles in the excited state. The results of mass spectrometer experiments have been presented. The results enable us to conclude that the hydrogen desorbed from the metal hydrides, in comparison with equilibrium one, has heightened molecules ionization cross-sections by electron impact and reduced potentials of hydrogen molecular ions generation.
