    • Abstract
  • p-t curves of hydrogen desorption by titanium hydride were investigated at 350-550 ℃ by using the methods of varying temperature and keeping temperature in a constant volume system. The desorption rate constants of hydrogen desorption by titanium hydride at different temperatures were determined by using the method of the reaction rate analysis. The obtained activation energy values of varying temperature and keeping temperature method are (22.1±2.5) and (27.1±0.4) kJ•mol－1, respectively. The result shows that the activation energy values obtained by keeping temperature method is precise.
