Özet

The regeneration of MnO/gamma-Al2O3 used as a sorbent to remove H2S from fuel gases was studied with a packed bed reactor. The sorbent was prepared by wet method in which MnO was impregnated onto a standard gamma-Al2O3 The sorbent was regenerated at 600 degrees C. The regenerating gas was a mixture of N-2, H-2 and steam in various proportions. The N-2-H-2-steam mixture resulted in a complete regeneration of the sorbent. The composition of the reactor off-gas varied according to the regenerating gas composition. Under suitable conditions the concentration of H2S in the reactor off-gas was high enough for use to produce elemental sulfur.
