Abstract:

A sorbent material, an activated carbon canister and a method are described which can be utilized to remove organic compounds from a vaporous stream with a relatively greater degree of safety, as compared to previously known methods. In the invention, essentially dry and wetted activated carbon particles are intermixed in a substantially homogeneous mixture which inhibits accidental combustion. The heat capacity of wetted carbon particles retards the heating of nearby unwetted particles, so as to inhibit the ignition of the nearby unwetted particles. The presence of wetted particles intermixed in the substantially homogeneous mixture has relatively little effect on the hydrocarbon adsorption performance of the mixture.
