columnar activated carbonMade from high-quality coal, coconut shell, and sawdust, refined using advanced technology, with a black amorphous particle appearance.

columnaractivated carbonIt is also widely used for the purification of toxic gases, exhaust gas treatment, purification of industrial and domestic water, solvent recovery, and other aspects.

Columnar activated carbon is applied in various aspects of industrial and agricultural production, such as alkali free deodorization (refined mercaptan removal) in the petrochemical industry, ethylene desalinated water (refined packing), catalyst carriers (palladium, platinum, rhodium, etc.), water purification, and sewage treatment; Water quality treatment and protection of power plants in the power industry; Chemical catalysts and carriers, gas purification, solvent recovery, and decolorization and refining of oils and fats in the chemical industry; Refining and decolorization of beverages, alcoholic beverages, monosodium glutamate mother liquor, and food in the food industry; Gold extraction and tailings recovery in the gold industry; Wastewater treatment, treatment of waste gas and harmful gases, and gas purification in the environmental protection industry; And related industries such as cigarette filters, moisture-proof wooden flooring, odor absorption, control of automobile gasoline evaporation pollution, preparation of various impregnating agent liquids, etc. Activated carbon will have excellent development prospects and a broad sales market in the future.

Columnar activated carbon has a good adsorption effect on volatile organic compounds in water, which can achieve a removal rate of 25% to 65% for various volatile organic compounds in water. Comparing the adsorption patterns of various organic compounds with different molecular weights, it can be seen that for volatile organic compounds, the larger the molecular weight, the higher their removal rate. This is similar to the adsorption law of phenol and cationic light yellow, that is, for small organic molecules in water, the larger the molecular weight, the easier it is to be adsorbed by activated carbon.

Activated carbon has a good removal effect on extractable organic compounds with a molecular weight of less than 480, while its removal efficiency for large molecular organic compounds is very low. This is mainly due to the steric hindrance effect of the microporous structure of activated carbon. Organic molecules that are too large cannot enter the pores of activated carbon and can only adsorb on the surface of activated carbon

The following conclusions were drawn by comparing the adsorption effects of activated carbon on volatile and organic compounds:

Activated carbon has significant differences in adsorption of volatile organic compounds and extractable organic compounds. The adsorption effect of volatile organic compounds increases with the increase of molecular weight, while the adsorption effect of extractable organic compounds increases with the decrease of molecular weight. This is mainly because volatile organic compounds are mainly organic compounds with relatively low polarity, while extractable organic compounds are organic compounds with relatively high polarity. Activated carbon itself can be seen as a non-polar adsorbent, with a greater adsorption capacity for non-polar substances in water than for polar substances. Moreover, when the size of adsorbate molecules is in a certain proportion to activated carbon, it is beneficial for adsorption. For molecules with smaller polarity, the larger the molecular weight, the more favorable it is for adsorption.

Main conclusion: Activated carbon has great competitiveness in adsorbing various organic compounds in water, and its adsorption capacity for various organic compounds is not only related to the molecular structure of the organic compounds, but also to the number of types of organic compounds in the water. Meanwhile, for volatile organic compounds and extractable organic compounds, the relationship between their adsorption capacity on activated carbon and molecular weight is completely opposite. As the molecular weight increases, the adsorption performance of extractable organic compounds decreases; As the molecular weight increases, the adsorption performance of volatile organic compounds also increases.

coal qualityColumnar activated carbon manufacturerDifferent materials have been developed for different purposes, and the variety of materials has been increasing. The mixing of so many different types of materials makes it difficult to recycle waste materials. Therefore, from the perspective of improving the recyclability of metal materials, it is ideal for all components of metal products to be manufactured from a single alloy system, and the fewer and simpler the types of alloy elements contained, the easier the regeneration cycle of coal columnar activated carbon.

From this perspective, a super universal alloy refers to a standard system alloy with a limited variety of alloy types that can meet various application requirements. For this purpose, it is necessary to have an alloy system that can meet universal characteristics (such as classification based on specific performance requirements such as heat resistance, corrosion resistance, and high strength for each type of component), such as columnar coal qualityActivated carbon manufacturerSpecific alloys can be made by changing only the composition ratio within the same alloy system (universal alloys). On the other hand, it is difficult to achieve consistent grade of waste during the regeneration cycle, and it is also difficult to avoid chemical composition changes caused by impurities. So, in order to facilitate regeneration and recycling, it is necessary to have an alloy system with low impact of composition changes on characteristics and good compatibility of coal columnar activated carbon composition changes.

General alloys are alloy systems composed of limited elements, and their properties can be changed on a large scale by changing their ratios. Coal columnarActivated carbon plantHome can be listed as follows: Steel series: By changing the relative content, a series of steel grades such as ferritic steel to stainless steel can be obtained, and the microstructure and properties of these steels vary greatly. The change in relative content of coal columnar activated carbon can cause significant changes in the microstructure and properties of the alloy. Various types of steel are widely used in practical applications, and there has been significant progress in research and development
