Activated carbon circulability

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.https://www.yrdcarbon.com/
The adsorption properties of activated carbon fiber or modified activated carbon should be further studied.
Activated carbon desulfurization and denitration technology will be a promising technology for the combined removal of pollutants from coal burning.Preparation method of granular activated carbon is mainly physical activation method [12 and chemical activation method [3.821]. Physical activation method is to dry, carbonized materials will be first, and then carbonized material crushing, then add to the crushing carbonized material, the binder and its mixing, forming and drying grain charcoal, then the granular activated carbon under a certain temperature, the final results of dry granular activated carbon products. The method commonly used activation main gas water vapor and carbon dioxide [20] [l ⒂ 5]. The physical activation method is characterized by high activation temperature (generally at about 900 ℃), the equipment investment is large, step trival,
But the pollution to the environment is relatively small.https://www.yrdcarbon.com/products/activated-carbon/
Chemical activation method is to mix raw materials with chemicals in a certain proportion, impregnation for a period of time, kneading and plasticizing at an appropriate temperature, and then carbonization and activation are completed in one step.
The chemicals commonly used are ZNC12, H5PO and KOH.
At present, more research is done on H;
Particle strength is also a main index of granular activated carbon.
In order to improve the particle strength of granular activated carbon, usually take some special processing measures, such as adding some help plasticizing material and proper mechanical processing [14] or control in the process of kneading kneading temperature and kneading time, can greatly improve the strength of granular activated carbon particles, making the strength of the granular activated carbon has reached the fruit shell carbon intensity index.
