CO2 capture by activated and impregnated anthracites
The adsorption capacity of the activated anthracites decreases rapidly with increasing adsorption temperature, probably due to the adsorption being a physisorption process. The anthracite with the highest CO 2 adsorption capacity is the sample activated at 800 °C for 2 h, whose surface area was only 540 m 2 /g, and the adsorbed amount of …
Water Handbook
Quartz sand, silica sand, anthracite coal, garnet, magnetite, and other materials may be used as filtration media. Silica sand and anthracite are the most commonly used types. When silica is not suitable (e.g., in filters following a hot process softener where the treated water is intended for boiler feed), anthracite is usually used.
