| Outline of Final Research Achievements |
The studies of the development of nickel catalyst for the hydrogenation of nitrate in water to nitrogen were carried out. Hydrogenation reaction using nickel particles predominantly having (100) or (111) facet revealed that the reaction is not a structure-sensitive reaction. Meanwhile, it was found that the nitrogen selectivity was increased with the increase in the nickel crystallite size.
The structure and the crystallinity of Raney nickel catalyst were changed by the calcination before reaching process. This treatment resulted in 100% conversion and 40-60% nitrogen selectivity. The addition of auxiliary metal, such as molybdenum to Raney nickel increased the stability of the catalyst.
