The potential for the use of multi-walled carbon nanotubes (MWCNTs) for the adsorption of ammonia in solid-gas adsorption refrigeration applications has been investigated by experimental determination of ammonia adsorption properties, as well as the thermal conductivity of a composite adsorption material. In addition to this, two models for estimating the adsorption of ammonia on MWCNTs were evaluated. It was determined that the adsorption amount of ammonia on MWCNTs at equilibrium ...
