<p>A deacidification agent was prepared through incipient-wetness impregnation method, by using activated γ-Al2O3 as the carrier material to loaded Na2CO3, which can simultaneously remove HCl, H2S and carbonyl sulfur (COS) from blast furnace gas. The pretreatment at temperature of 550°C can improve the dechlorination performance. The maximum breakthrough time, penetration chlorine capacity, and the highest utilization rate of active component of deacidification agents were 47.5 h, 11.59%, and 75.6%, respectively. The deacidification agents can not only be used as active component to remove H2S from blast furnace gas, but also can act as a COS hydrolysis catalyst. HCl has no obvious effect on the desulfurization performance, while the sulfide gases inhibited the dechlorination process. The synergistic desulfurization and dechlorination experiment results show that the highest removal efficiencies for HCl, H2S and COS by the prepared deacidification agents were all above 99%.</p>
