| Outline of Final Research Achievements |
Ammonia absorption and desorption reactions with nickel chloride were focused for storing ammonia with high storage density. To establish the ammonia storage system, in this study, we have tried to prepare nickel chloride wire with high heat and mass transfer rate and to develop the ammonia reservoir equipped with the nickel chloride wires.
Chlorination behavior of nickel powder was first investigated with a thermogravimetric analyzer under various temperatures and chlorine gas pressures. Subsequently, nickel wire was chlorinated with a tubular reactor under various chlorination conditions. As a result, chlorination ratio increased linearly with time in every wire diameter and temperature. Within this experimental ranges, a maximum chlorination ratio was achieved at 873 K, chlorination gas pressure of 48.9 kPa, and reaction time of 360 min. However, it is also found that an increase in chlorination ratio and prevention of exfoliation of NiCl2-6NH3 are required toward practical use.
