| description | Methods and apparatus for providing the heat required to maintain the desired temperature for catalyst regeneration. The catalyst is heated by contacting a reactant gas mixture with the catalyst in order to initiate an exothermic reaction and, once the desired temperature is achieved, exposing the catalyst to a regenerating gas. The temperature may also be maintained by heating the reactant gas mixture prior to contacting the catalyst and/or adding a liquid, which may be heated, to the catalyst. For heating a Fischer-Tropsch catalyst for regeneration, the reactant gas preferably contains less than 12 mole percent carbon monoxide and more preferably contains between 1 and 4 mole percent carbon monoxide. |
