| الوصف: | The microwave-assisted chemical process is environmentally friendly and energy-saving. In this study, microwave irradiation was applied to enhance the hot coal gas desulfurization process with modified semi-coke-supported Fe2O3 as the sorbent. The results indicate that the sorbent with 20% Fe2O3 shows the greatest breakthrough sulfur capacity (9.0%) at 500 °C in the simulated coal gas. Besides Fe1–xS, sulfur was also produced during the desulfurization process. The deactivation model could be used to simulate the adsorption behavior of the sorbents for H2S. The activation energies of the sulfidation reaction by microwave and conventional techniques are 26.9 and 27.8 kJ mol–1, respectively. The sorbents adsorbing H2S under microwave irradiation show much larger initial rate constants (308–2071 m3 min–1 kg–1) for the sulfidation reaction. In comparison to the conventional technique, microwave desulfurization generally results in much better performance of H2S removal and leads to less negative effects on th... |
