Study of thermal conductivity, permeability, and adsorption

Thermal conductivity increased as the ratio of expanded graphite increased. Considering that the density of activated carbon for the composite adsorbent should not be lower than 200 kg/m(3), otherwise the volumetric cooling capacity would be unacceptably low, the highest thermal conductivity obtained from experiments was 2.47 W m(-1) K(-1).

Adsorption Behavior and Thermodynamic

The adsorption of p,p'-DDT onto expanded graphite (EG) in aqueous solutions was investigated under varying conditions of p,p'-DDT concentrations, adsorbent doses, pH, and contact time. The removal efficiency of p,p'-DDT from the aqueous solutions remained constant in a range of pH 2 to 10, and the thermodynamic data followed the type II adsorption isotherm characterized by a spontaneous
