| ABSTRACT |
|
The reaction between Mn-based sorbent and hydrogen sulfide was studied in the presence of coal derived fuel gases. The Mn-based sorbents were prepared using combinations of a MnC03, TiC>2, Fe203, and bentonite. The mechanical strength of the Mn-based sorbent was highly sensitive to the induration temperature. The sulfidation of Mn-based sorbent was examined in a packed-bed reactor at temperatures ranging from 500 to 750°C, using simulated coal gas containing 1% of H2S and HC1 concentrations of 0, 630, and 1260 ppmv. Some agglomerations of the particle were observed in the spent sorbents, but did not show any detectable difference between the morphologies of the fresh, sulfided, and regenerated sorbents. In this experimental study, all the HC1 concentrations revealed no harmful effects on the capability of the Mn-based sorbent to remove H2S from the simulated fuel gas. The presence of the HCI in the simulated fuel gas to some extent enhanced the desulfurization efficiency under the sulfidation conditions employed in this study. |
