Abstract
A novel composite strontium chloride (SrCl2) is developed with porous material of expanded natural graphite (ENG) and nanoparticle of carbon coated nickel (Ni@C) as the additives. Thermo-physical properties such as thermal diffusivity, thermal conductivity and permeability are investigated and analyzed. The highest thermal diffusivity could reach 6.2âmm2â
sâ1. Correspondingly the highest thermal conductivity is 4.03 Wââ
âmâ1ââ
âKâ1, which is about 20 times higher than that of granular SrCl2. Permeability of novel composite SrCl2 ranges from 1.31âÃâ10â9 m2 to 1.07âÃâ10â13 m2. Moreover, samples with Ni@C have better sorption performance in ammonia than those without Ni@C due to the improved heat and mass transfer performance. Ammonia sorption quantities of novel composite SrCl2 range from 0.39âkgâ
kgâ1 to 0.67âkgâ
kgâ1 when evaporation temperature varies from â15â°C to 15â°C. The addition of ENG and Ni@C shows great potentials for sorption refrigeration by adjusting the concentration swing.
