Can you give best quality Activated Carbon Fiber supplier or Manufacture. I am working on Solar Assisted Adsorption Refrigerator, in which ACF is used as a adsorbent.
Well, it depends on what you plan to adsorb: water, ammonia, ...? The most critical issue of activated carbons for refrigeration is their low thermal conductivity, seriously limiting the power of the refrigeration system. So the adorbent should be associated with a thermally conducting material. This is the main problem, probably more significant than the choice of the most relevant porosity and surface area.

ACFs ensure rapid adsorption/desorption time and higher adsorption capacity per unit mass of adsorbent. Water, ammonia, carbon dioxide, acetone, methanol, ethanol and gasoline vapor have been tested but, ethanol appears to be the most favorable working pair for ACF. An important point is the packing of the adsorbent.
