In cryo-sorption vacuum pump applications, activated carbons are the most considered adsorbent for a multitude of reasons like broad adsorption range, better adsorption area, low-temperature operation stability, and regeneration characteristics. The superior heat transfer capabilities of adsorbents are desirable, for rapid cooling and uniform temperature distribution of adsorptive surface, shorter regeneration cycles, and easy removal of heat of adsorption. The thermal conductivity of normal activated carbons can be enhanced by developing composites of activated carbon with conductive metals as fillers in limited quantities, without degrading the adsorptive characteristics. Metal powders can be physically mixed with activated carbon with or without using chemical binders or can be chemically impregnated. In this study, the chemical impregnation of copper on activated carbon was explored. Activated carbon samples with varying copper-carbon weight ratios were synthesized using the incipient wetness method. The thermal conductivity values of these samples were subsequently tested and reported at 80 K.
