Honeycomb type iron oxide sorbent, which removes H2S and COS in hot coal gas, has been developed. The sorbent must be regenerable. In this paper, the regeneration characteristics and the characteristics of H2S removal during desulfurization-regeneration cycles are evaluated. The sorbent was regenerated using 1.5% O-2 containing gas and it was found that over 570 K, more than 60% of sulfur absorbed during desulfurization is removed, Nevertheless it was also found that over 570 K, if SO2 is introduced with the regeneration gas, it is absorbed by regenerated Fe2O3. This result indicates that the regeneration process should be stop as soon as possible when regeneration reaction ends. The residual sulfur in the sorbent after regeneration was decomposed and SO was released during desulfurization. In order to prevent 502 release, a reduction process, in which the residual sulfur is decomposed by coal gas at more than 630 K, is needed. In desulfurization - regeneration cycles test with reduction process, it was found that our sorbent has a beneficial effect in the sense that desulfurization performance became stable at more than 5 cycles.
