Zeocarbon (also called activated charcoal and zeolite mixture) is the more general term which 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.

Production and Re-activation
It can generally be produced mixing activated carbon and zeolite.
Saturated zeocarbon can be regenerated by heating.
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.
Zeocarbon is used in air purification (especially in home plumbing vent pipes), wastewater treatment, filters in compressed air and gas purification, and many other applications.
Zeocarbon absorption has numerous applications in removing pollutants from air streams both in the field and in industrial processes such as:
Zeocarbon overcomes the limitations of activated carbon alone by allowing the mixture to bind well to:
Filters with zeocarbon are usually used in compressed air and gas purification to remove oil vapour, odor, and other hydrocarbons from compressed air and gas. The most common designs use a 1 stage or 2 stage filtration principle where zeocarbon is embedded inside the filter media.
