Nf. Fedorov et al., INFLUENCE OF EXTERNAL SURFACE TEXTURE OF ACTIVATED CARBONS ON THEIR KINETIC CHARACTERISTICS, Journal of applied chemistry of the USSR, 65(7), 1992, pp. 1296-1300
The external surface of adsorbents has been modified by various method
s to impart roughness, and the effects of such modification on the kin
etics of vapor sorption have been investigated. A positive effect is m
anifested mainly at low flow rates, where the limiting stage is extern
al diffusion.
