ABSTRACT:
A method and apparatus for treating synthesized gas ("syngas") comprises introducing the syngas into a lower portion of a vessel. The syngas flows in the lower portion through a static regenerative hot gravel bed and into an upper portion of the vessel containing particulate material at a temperature less than that of the syngas in a manner so that the material reduces the temperature of the syngas and reacts with the syngas to abate pollutants therein, and the syngas entrains at least a portion of the material. The entrained material is then separated from the gas, cooled in a heat exchanger, and returned to the vessel, while the separated syngas is passed to downstream facilities.
