ABSTRACT:
A method is described to reactivating contaminated particulate adsorbent material. A gas stream is passed through the adsorbent material. The gas stream comprises hydrogen, carbon monoxide and steam, and is substantially free of unbound oxygen. The temperature and flow rate of the gas stream is selected to volatilize organic compounds adsorbed by the adsorbent material. Thereafter, the gas stream is reacted with steam at a temperature of at least 700.degree. F. The steam with which the gas stream is reacted is in excess of the stoichiometric amount required to react with substantially all of the organic compounds in the gas stream. Thereafter the gas stream is circulated back to the adsorbent material for further passing therethrough. The cycle is continued until the level of contamination of the adsorbent material is below a predetermined level.
