Although the removal efficiency of the activated carbon on SO2 and NO measured in this test is low, the activated carbon used in circulating fluidized bed flue gas desulfurization and denitration has the advantages of simple and reliable process, low system resistance, stable desulfurization and denitration, good economic and environmental protection, NO secondary pollution and so on.
The adsorption properties of activated carbon fiber or modified activated carbon should be further studied.coconut shell activated carbon price
Activated carbon desulfurization and denitration technology will be a promising technology for the combined removal of pollutants from coal burning.
In addition, the adsorption capacity of activated carbon also has a great relationship with its internal pore structure, pore size distribution and surface chemical properties.
Chemical method in addition to a certain microporous, macroporous, there are more mesopore (transition hole), so more suitable for the application of liquid phase, adsorption of larger points · sub material, such as sugar solution has a very good decolorization effect;
When purifying water quality, it can also remove the colored material well and achieve the specified chroma requirements.Some of the adsorbed substances are concentrated on the surface of the activated carbon first, and then are adsorbed between atoms or molecules of the solid lattice, and some special substances are combined with the activated carbon molecules and are adsorbed.
When activated carbon on the water containing impurities adsorption, dissolved impurities in the water on the surface of activated carbon accumulation and adsorption, but also some of the adsorbed material due to molecular movement and left the surface of activated carbon, re-enter the water at the same time the phenomenon of desorption.coconut shell carbon
When adsorption and desorption are in a state of dynamic equilibrium, it is called adsorption equilibrium.Therefore, the decolorization with activated carbon is the best in aqueous solution, followed by ethanol and acetone, and almost no decolorization ability in other organic solvents.
The size of the adsorption force of activated carbon on the solute in the solution, in addition to the size of the activated carbon and the structure of the adsorbed matter, must also consider the interaction between solute and solvent, that is, must also consider the size of the solute solubility of the solvent.
Activated carbon chromatography is often carried out in an aqueous solution, the solubility of the adsorbate in water when there is a key role in the adsorption capacity or adsorption stability.
For example, the adsorption of activated carbon on iodine, flash iodine in the water towel solubility is minimum, so the adsorption of activated carbon in water is the largest.
