For the purpose of the gradual decrease of calcium carbonate resources and reduction of carbon emissions in wet flue gas desulfurization process, the utilization process of carbide slag to replace limestone is systematically analyzed. The properties of carbide slag and limestone have been analyzed, and the mass transfer and reaction behaviors in de...

High carbon consumption is an important factor restricting the wide application of activated carbon technology for flue gas purification. A fixed-bed reactor combined with a Fourier transform infrared (FTIR) spectrometer was used to explore the source of carbon consumption at various SO2 concentrations and cyclic adsorption-regeneration times. The ...

With the vigorous development of China's iron and steel industry and the introduction of ultra-low emission policies, the emission of pollutants such as SO2 and NOx has received unprecedented attention. Considering the increase of the proportion of semi-dry desulfurization technology in the desulfurization process, several semi-dry desulphurization...

The sulfur dioxide (SO2) contained in combustion exhaust gases from medium-scale facilities or ocean ships must be removed because of its role as an air pollutant. In this study, dry DeSO(x) filter of manganese oxide was used to capture SO2 with a simple sulfate reaction. The thermogravimetry (TG), experiments shows that the MnO2 sample having a sp...
The removal of sulfur dioxide (SO2) contained in the combustion exhaust gas from medium-scale facilities is necessary because of its role as an air pollutant. In this study, we focus on dry DeSO(x) filters that use simple desulfurization materials to capture SO2; in particular, we used manganese dioxide (MnO2) that takes part in the sulfation (MnO2...
A series of sorbents for flue gas SO2 scrubbing have been prepared from hydrated lime (HL) and blast furnace slag (BFS) with the factorial experiment design method. The sorbents were characterized and tested for SO, reactivity in a differential fixed-bed reactor. It was found that, due to the formation of calcium silicate hydrates (CSHs), the react...
