Zeocarbon
Encyclopedia
Zeocarbon includes material mostly derived from charcoal and volcanic rock
. It denotes a material which has an exceptionally high surface area, typically determined by nitrogen adsorption, and includes a large amount of microporosity. Sufficient activation for useful applications may come solely from the high surface area to enhance the absorbing properties of the material.
Volcanic rock
Volcanic rock is a rock formed from magma erupted from a volcano. In other words, it is an igneous rock of volcanic origin...

Production and Re-activation
It can generally be produced mixing activated carbon and zeolite.- Chemical re-activation: Mostly acids are mixed with the source material in order to cauterize the fine pores. This technique can be problematic because, for example, zinc trace residues may remain in the end product.
- Steam re-activation: The material is mixed with vapours and|or gases at high temperature to activate it.
- Saturated zeocarbon can be regenerated by heating.
Properties
Zeocarbon may have a surface area in excess of 500 m²/g, with 1000 m²/gram being readily achievable. A tennis court is about 258 m².Applications
Zeocarbon is used in air purification, wastewater treatment, filters in compressed air and gas purification, and many other applications.Environmental applications
Zeocarbon absorption has numerous applications in removing pollutants from air streams both in the field and in industrial processes such as:- Volatile organic compound capture from household plumbing, painting, dry cleaning and other processes
- Zeocarbon overcomes the limitations of activated carbon alone by allowing the mixture to bind well to:
- Alcohol (such as ethanolEthanolEthanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a psychoactive drug and one of the oldest recreational drugs. Best known as the type of alcohol found in alcoholic beverages, it is also used in thermometers, as a...
