Porous structure of active carbon and ASC whetlerites produced therefrom

摘要: A set of samples, including active carbon and ASC-whetlerites, both in their original form after extraction, all with an identical carbonaceous skeleton, was investigated to specify the porous structure deposition impregnant. Mercury porosimetry adsorption nitrogen dioxide were used for this purpose. The thickness deposited layer increases pore radius. In macropores r ~ 1000 nm largest relative frequency, impregnant is about 120 nm. deposit may somewhat remove unevenness walls, but, on other hand, it creates a secondary macropores, where high enough. Also partial clogging small pores takes place.
