In literature:

Enormous quantities of charcoal are produced; in short, on all sides there is evidence of mining activity.

In news:

In the plant we pressure filter active charcoal suspensions from a batch reactor (stirred tank) through a three-stage filter system: a 5 um bag filter, a 1 um cartridge filter, and a 0.2 um (absolute) cartridge filter.
Attendees chose miniature plants for their terrariums and learned how to put the tiny gardens together, using moss, activated charcoal, soil, rocks and props.
In general, it is best to apply activated charcoal or fine-textured.
We experience variable filtration time of suspensions of different batches of active charcoal and would like to evaluate the performance of the filter media on a lab scale (0.5 - 5 L).
The strips contain activated charcoal that draws tarnish -causing gases from the air.
Activated Charcoal is a Must.

In science:

We have succeeded removing 222Rn from gas phase using cooled (−100◦C) activated charcoals with more than 90% efficiency, however as the flow rate of gas circulation is limited by the cooling power of the condenser, Rn removal from liquid is preferable.
Activated charcoal or some other catalyst is needed to accelerate the ortho/para conversion.
Experimental Quantum Computation with Nuclear Spins in Liquid Solution
The idea is to concentrate Radon emanation into a Radon trap like active charcoal or organic zeolith and then to measure Radon from the trap.

The usual technique (Radon trap by active charcoal at −50 degrees) can be applied to purify Helium gas.
