Method and adsorbent for dry exhaust gas purification

摘要

Process for dry purification of waste gases from thermal processes comprises contacting the waste gas stream with coke or activated charcoal as powdered adsorbent. A catalyst inhibitor is additionally added to the waste gas stream or the waste gas stream is contacted with it. An Independent claim is also included for the adsorbent used in the process comprising activated charcoal or coke with an addition of 1-10, preferably 1-2 wt.% catalyst inhibitor.
