| Research Abstract |
The experiment was done in the batch device using the autoclave. We tested it at 180 degrees Celsius this time. The formation rates of NH4I from the nitrogen HI increased every time. A value of 3. 60 and 3. 96 was provided each as NH4+density[ mg/L]. But this vales showed the 0. 31mol% of conversion of N_2 in comparison with the equilibrium level of 15mol%. This results showed that a catalyst was necessary for this reaction. We showed the activity that Ru was the highest activity in Ru, Pt, the Rh. Reaction rate of the degree to double 1. 5～2 in comparison with no catalyst was provided. By the experiment of three kinds of supporting materials, in Al2O3, ZrO2, Ta2O5, SiO2 the supporting material of Al_2O_3 was proved to be the highest reaction rate.
