1. A method for avoiding self combustion of a carbonaceous adsorbent comprising a catalyst, the method comprising

providing a carbonaceous adsorbent comprising one or more contaminants adsorbed on the carbonaceous adsorbent and where one or more of the contaminants are in a reduced state;

regenerating the carbonaceous adsorbent in a thermal regeneration process; and

blowing air through said carbonaceous adsorbent prior to and subsequent to regeneration of the carbonaceous adsorbent thereby oxidizing the catalyst and/or components that are in a reduced state and simultaneously cooling the carbonaceous adsorbent.
