The Classification of Activated Carbon
Activated carbon from the appearance and shape of the point of view, there are powdered activated carbon, granular activated carbon, fiber activated carbon. Granular activated carbon includes amorphous granular carbon, columnar activated carbon, spherical activated carbon, hollow spherical activated carbon and microsphere carbon, etc.
Each kind of carbon has several or a dozen different uses of carbon, such as powdered carbon chemical carbon, sugar carbon, medicinal carbon, injection carbon and water purification carbon; Granular carbon has clearance carbon, water purification carbon, desulfurization carbon, dechlorination carbon, decolorization carbon, carrier carbon, solvent recovery carbon, monosodium glutamate carbon, gold smelting carbon, venilen carrier carbon and gas mask carbon. Of course, there are some special carbon, such as microsphere carbon (blood purification), high specific surface area activated carbon (storage carbon) and carbon molecular sieve (for pressure swing adsorption) and so on.
If you want to evaluate the performance and adsorption characteristics of activated carbon, according to the different uses and requirements of activated carbon, the appropriate indicators are used. The main indicators of activated carbon are particle size, specific surface area, pore volume, pore distribution, true density, particle density, bulk density, strength, moisture, ash and so on; The adsorption properties of activated carbon were characterized by benzene adsorption rate, carbon tetrachloride activity, iodine value, phenol value, sugar density value, caramel value, acetic acid adsorption value, zinc acetate value and methylene blue value. Of course, there are some special purpose indicators.
