Re: Air absorbtion by charcoal.

Hi.
I would like to know if activated charcoal absorbs air under pressure.
FE if I have a vessel containing air close to atmospheric pressure and
atmospheric temperatures, but which is subject to pressures fluctuations
of 2-3 PSI, will activated charcoal act to reduce the pressure fluctuations?
advice appreciated.

You'll get some prompt hysteresis from gas viscosity in porosity.
You'll get some slow hysteresis from adsorption and desorption.
Wouldn't it make more sense to install a pneumatic dashpot (e.g.,
slowed bellows)?
