Study on Synergistic Desulfurization and Chlorine Resistance of Alkaline Metal Oxides@ZrO2/γ-Al2O3-Loaded Catalysts
In this article, the atmospheric pollutants carbonyl sulfide (COS) and HCl in blast furnace gas are taken as the research object. Catalysts with γ-Al2O3 as carrier and alkaline metal oxides as active components are prepared for the synergistic desulfurization and chlorine resistance of blast furnace gas. The results show that the CaO–ZrO2/γ-Al2O3 hydrolysis catalyst has the best performance. The removal rate of COS is maintained at more than 95 wt%, and the maximum can reach 99 wt%, and the overflow rate of H2S is also maintained at more than 80%. At the same time, the synergistic desulfurization and chlorine resistance treatment efficiency of CaO–ZrO2/γ-Al2O3 hydrolysis catalyst is maintained at about 90%. This work provides an effective reference for the synergistic removal of acidic and harmful components in actual industrial blast furnace gas.
