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 improve dechlorination performance. maximum breakthrough time, penetration chlorine capacity, highest utilization rate active component agents were 47.5 h, 11.59%, 75.6%, respectively. not only be used gas, but...
The effect of carbon dioxide (CO2) on the desulfurization sintering flue gas with hydrate (Ca(OH)2) as an absorbent was investigated, and formation calcium carbonate (CaCO3) its discussed. competitive relationship between sulfur (SO2) deacidification agent in is discussed thermodynamically, showing that sulfates are more likely to be generated under high oxygen potential conditions SO2 reacts preferentially than CO2 a thermodynamic standard state. amount produced CaCO3 increases condition...
This study focuses on the investigation of variation mechanism in situ generated calcium carbonate (CaCO3) during simultaneous removal process simulated sintering flue gas. The experiment was performed to investigate synthetic behavior SO2, NO2, and CO2 under gas condition. Samples were obtained at different stages characterize analyze their compositions. influence CaCO3 effect desulfurization denitrification are discussed. During process, pore structure sorbent is reshaping with fewer...
