Columnar activated carbon for toxic gas purification, waste gas treatment, industrial and domestic water purification treatment, solvent recovery is also more extensive.

The columnar activated carbon used in industrial and agricultural production, such as petrochemical industry CAUSTIC-FREE (refined mercaptan), ethylene desalted water (refined filler), catalyst (palladium, platinum, rhodium, etc.), water purification and sewage treatment; electric power industry and the power plant water treatment and protection of chemical industry; the chemical catalyst and carrier, gas purification, solvent recovery and oil decolorization, refining; food beverage industry, wine, liquorAnd foodmsgrefining, decolorization; gold extraction solution, recovery of gold industry; environmental protection industry wastewater treatment, waste gas and harmful gas treatment, gas purification; cigarette filter, wood flooringmoisture, suction control taste, automotive gasoline evaporation pollution and related industries, various impregnating agent such as liquid preparation. Activated carbon will have an excellent development prospect and broad market in the future.

Column activated carbon has better adsorption effect on volatile organic compounds in water, and can remove various volatile organic compounds in water body to 25%~65%. Comparing the adsorption law of different molecular weight organic compounds, it can be seen that for volatile organic compounds, the greater the molecular weight, the higher the removal rate. The adsorption of cationic and phenol and similar to that for the small molecule organic matter in water, the higher the molecular weight, the more easily adsorbed by activated carbon.

Activated carbon has a good removal effect on extractable organic matter with molecular weight less than 480, while the removal efficiency of macromolecular organics is very low. This is mainly due to the microporous structure of activated carbon, steric hindrance effect, too large organic molecules can not enter the pores of activated carbon, only adsorbed on the surface of activated carbon

By comparing the adsorption effect of volatile carbon and organic compounds on activated carbon, the following conclusions are obtained:

The adsorption of volatile organic compounds and extractable organic compounds is very different from activated carbon. With the increase of molecular weight, the adsorption effect of volatile organic compounds is better, and the organic adsorption can be better with the decrease of molecular weight. This is mainly due to the volatile organic matter is mainly some smaller polarity of organic matter, and the extractable organic matter is the polarity of organic matter is relatively large, activated carbon itself can be seen as a non-polar adsorbent for water adsorption capacity of nonpolar substances is greater than the adsorption capacity of polar substances. Moreover, when the molecular size of adsorbate is in a certain proportion with activated carbon, it is most favorable for adsorption. For the less polar molecules, the greater the molecular weight, the more favorable for adsorption.

The main conclusion: the adsorption of various organic compounds in water by activated carbon has great competitive, the adsorption of various organic compounds is not only the size and molecular structure of organic compounds, and the types of organic matter in water amount on. At the same time, for volatile organic compounds and extractable organic compounds, their adsorption capacity on activated carbon is opposite to that of molecular weight. The extractable organic matter decreased with the increase of molecular weight, while the adsorption capacity of volatile organic compounds increased with the increase of molecular weight.

Coal columnar activated carbon manufacturers have developed different materials for different purposes, and the types of materials have been increasing. With so many different kinds of materials mixed together, recycling of waste material is difficult. Therefore, from this point of view to improve the recycling of metal materials, all parts of metal products by a single alloy manufacturing system is the ideal, and the type of alloy elements contained less the more simple, coal columnar activated carbon regeneration cycle more easily.
