Pressure Swing Absorption and Desorption of Ammonia in Calcium Halide Solid Mixtures.

ABSTRACT: The absorption and desorption behaviors of NH₃ in solid CaCl₂-CaBr₂ were investigated using the pressure-swing method at 473 K. Various compositions of CaCl₂-CaBr₂ solid mixture particles were formed by the impregnation method, and the solid-mixture effect on the NH₃ absorption behavior was evaluated. The compositional changes in the lattice sizes followed Vegard's law. For the solid mixture, the absorption rate of NH₃ increased because NH₃ was absorbed into CaCl₂-CaBr₂ at a lower energy and higher rate than CaCl₂ single salt. For x = 1.67 in CaCl _x Br_2-x , the highest storage capacity was obtained; however, NH₃ desor
