Removal of sulfur at high temperatures using iron

Abstract This paper deals with the simultaneous removal of H 2 S and COS in the temperature range of 400–650 °C at 1 bar by using iron-based sorbents. The iron-based sorbents were prepared using iron oxide and cerium oxide with coal fine ash as the support. Simulated coal gas was used in the sulfidation experiments and 5% O 2 in N 2 gas was used for regeneration of sorbents.
