A review on the solid sorption mechanism and kinetic models of metal halide-ammonia working pairs

Solid sorption and kinetic models are important for both experimental and theoretical analysis of chemisorption refrigeration and energy storage. This review attempts to present clear overview of the reaction kinetics of chemisorption working pairs (mainly the metal halide-ammonia working pairs). The typical equilibrium principles and phenomena in metal halide-ammonia working pairs are introduced. The advantages and shortcomings of several classical non-equilibrium models have been analyzed comprehensively and new chemisorption phenomena of metal halide-ammonia working pairs that have been recently discovered are discussed. Finally, new directions for the development of kinetic models for metal halide-ammonia working pairs are proposed.
