Conservation image Performance of Pollutant Adsorbents (2001–2003)

The packed gas tube on the right contains pellets of adsorbent spaced between white, irregular pieces of Teflon. The path of the gas flow is sufficiently mixed that when coupled with a very long residence time all of the pollutant has had time to react with the adsorbent. Photo: Jeffrey Levin.
