Absorption is a unique feature of activated carbon. The ability to absorb SO2 is closely related to its bulk density, porosity, isomerization of nitrogen functional groups in the surface, isomerization of oxygen functional groups, and the pH of the surface. powdered activated carbon pac So, what are the harmful practices of the surface characteristics of activated carbon raw materials on flue gas desulfurization characteristics?
The hazard of activated carbon surface layer characteristics on flue gas desulfurization characteristics
- The hazards of porosity structure and bulk density are based on the different molecular structure absorption methods in different specifications of porosity. The tiny pores in the carbon can be divided into the following three categories; w (w-Porewidth)> 50nm is the hole;
- The harm of the isomerization of the middle nitrogen functional group The isomerization of the middle nitrogen functional group has a great harm to the characteristics of activated carbon. The high temperature treatment of activated carbon with NHs and HCN can significantly improve the specificity of the catalytic response of activated carbon.
The harm of oxygen content functional group isomerism is related to the specific harm of oxygen content functional group isomerism on activated carbon flue gas desulfurization. activated carbon pellets for air filter uk It is generally believed that the oxygen content functional group isomerism is not good for flue gas desulfurization because it blocks the absorption of SO2 on activated carbon. Command; After the activated carbon air is oxidized with concentrated HNO3, the ability of activated carbon to absorb SO2, the ability to oxidize SO2 air to SO3, and the ability to adsorb H2SO4 have been significantly improved.
Surface loaded metal materials and the hazards of metal materials chemical substances The surface loaded metal materials of activated carbon raw materials can accelerate the chemical reaction rate of SO2 conversion to SO3.
The correlation between the relative density of activated carbon and the iodine value of activated carbon is different. The relative density of activated carbon is different and the iodine value is also different. The key science in this article is to study the correlation between the relative density of coal-based activated carbon and the iodine value of activated carbon.
