Absorptive separation of synthesized ammonia with metal halides

摘要

Ammonia absorption behavior of metal halide, as ammonia storage material for "New de-NOx process with a ma on-site synthesis" which was proposed by our group, was studied. Interaction between metal ion and ammonia was changed by hydration or mixing of metal halide, and ammonia absorption behavior of metal mixed halide was quite different from normal metal halide. Reversible ammonia absorption pressure and desorption pressure of CaCl_(2-x)Br_x was useful for ammonia storage with pressure swing cycle between 10 approx 60 kPa, and ammonia absorption capacity of CaCl_(2-x)Br_x was much more higher than acid treated active carbon and ion exchanged zeolite.
