Anthracite coal is hard and contains a high amount of carbon. Its dense structure and elevated ash content, resulting from prolonged mineralization, pose challenges for activated carbon production.
FT-IR fitting spectra of anthracite showed peaks that correspond to the oxygen-containing functional groups, including OH-N hydrogen, ring hydrogen and OH-ether hydrogen bonds in the 3600-3000 cm-1 band.
This solid adsorbent is inert and removes various dissolved contaminants. It can be made out of a wide range of materials such as wood, coal and coconut shells. It can be chemically and thermally activated.
Depending on the starting material and activation method, it may have either macropores or micropores. These pores give the carbon its high surface area that is important for adsorption.
A carbon's performance is affected by the diameter of its pores. Carbons with larger pores are better for applications involving gas, where chemicals must travel further inside the carbon.
Iodine numbers are also affected by the size of the pores. This is how easy it will be for a carbon to remove chlorine or odors. The higher the iodine value, the better carbon performs in removing contaminants.
Anthracite, which is graded according to its intended use, can be used for a number of purposes in the industry. Graded anthracite can be used for metallurgical refining and processing, power generation, heating for brick kilns, fuel for residential/commercial space heating and water/sewage filtration.
The anthracite is also used as a filler in plastics. Unique properties of this coal are its stiffness, strength, resistance to environmental stress cracking, and temperature at which heat is deflected. This carbon has less ash in it than most other fillers and can also be thermally processed to make graphene sheets.
Reading Anthracite (also known as Reading Hard Coal) is a coal firm that concentrates on mining, distribution and customization of anthracite to suit various industrial needs. Their anthracite has been carefully screened, graded, milled in accordance with specifications, delivered according to a schedule, etc. Their surface-mining in Pennsylvania produces quality anthracite, which is ideal for use as a sand filter in water or sewage. Anthracite, because it retains little moisture, is an excellent component in multilayer sand-filters.
Reagglomerated Anthracite is the perfect media for industrial and municipal aqueous water applications. Its rich, granular texture, coupled with its high physical strength makes it ideal. This media is commonly used along with Filter Sand for dual- and multi-media filters. This combination allows a higher void percentage and removes turbidity and SS more effectively than pure sand alone.
It has been demonstrated that copper acetate can increase anthracite's reactivity, characterized as lower ignition temperatures and shorter ignition delay times. The fraction with the largest particle size has the strongest impact.
Results from a recent pilot study of anthracite in place of GAC (granular activated carbon) in the treatment of surface water found that reagglomerated anthracite performed equal to or better than a high-purity GAC for all measured parameters (TOC, UV254 absorbance and TTHMs). The results show that an agglomeration method can achieve similar performance as high-purity GAC in treating surface water and groundwater.
Activated clay is used to absorb materials like pesticides and herbicides. This material can adsorb other gases, such as formaldehyde. The material is safe for the environment and does not contain toxic chemicals. This makes it an ideal material to adsorb dangerous chemicals out of water and air. This material is also capable of retaining its structure and can reactivated.
Bentonite, the raw material for this product is processed and then activated through inorganic acidification. The clay is then granulated or pelletized. The clay is then granulated and pelleted. Also, it is cheaper than chemically derived adsorbents.
The thermally activated clay can be used in cement and high-performance concrete to improve the quality, economy, and durability of Portland cement. To use this product successfully, you need to have precise temperature control and short retention times. In addition, the system can be designed to reduce fuel consumption and lower fossil CO2 emissions. thyssenkrupp has successfully applied this technology at cement plants across North America, Africa and Europe.
