| 摘要: |
The selective oxidation of hydrogen sulfide (H2S) to sulfur on activated carbon-supported metal oxide
sorbents (M/AC) was investigated for hot fuel gas desulfurization. Various M/AC sorbents loaded with
1 wt.% metal oxide were separately prepared by pore volume impregnation and their breakthrough
capacity was examined. The results showed that the breakthrough capacity of different sorbents can
be placed in the following order: Mn/AC > Cu/AC > Fe/AC > Ce/AC > Co/AC > V/AC. The metal oxides
loaded on the M/AC surface catalyze the reaction between hydrogen sulfide and oxygen to form element
sulfur; the activated carbon, as an adsorbent, can adsorb and store the element sulfur in its pore passage.
The DTG analysis and determination of forms of sulfur confirmed that the main product of the catalytic
oxidation of hydrogen sulfide was elemental sulfur. The regeneration of exhausted sorbents was carried
out using hot gas N2 and H2O desorption methods at temperature 500 C. The breakthrough capacity of
the sorbent was mostly recovered after regeneration. The mechanism of the catalytic oxidation of H2S on
M/AC sorbent was also discussed. |
