The competing role of moisture in adsorption of gaseous benzene on microporous carbon

The effects of moisture on adsorption of gaseous benzene have been investigated using microporous activated carbon (AC). Here, the performance metrics of an AC bed are explored in terms of the interplay between benzene concentrations (1–20 Pa) and relative humidity (RH, 0–100%). At lower benzene levels (<10 Pa), the adsorption capacity of AC bed was affected sensitively by water vapor with the performance reduction by 27–65% at 100% RH (e.g.,...
