Sorbostriction of FAS-3 microporous carbon adsorbent upon vapor adsorption from a flow of nitrogen carrier gas

Аннотация

Sorbostriction (adsorption-induced deformation) of FAS-3 microporous carbon adsorbent is investigated under dynamic conditions upon adsorption of benzene, carbon tetrachloride, and n-hexane vapors from a flow of nitrogen carrier gas at 573 K. The values of maximum deformation and corresponding times depend on the amount of an adsorptive. The peak time of sorbostriction curves is different for each substance under study, which makes it possible to use the effect of wavelike sorbostriction for the development of sensors for the control of qualitative and quantitative compositions of gas mixtures.
