Pitch, carbon fibres manufactured from

Isotherms of various microporous solids (activated carbons, zeolites, ACF s), involving different adsorbates (N2, CO2, Ar), have been measured Norit R1 Extra (N2, CO2), Norit RBI (N2), Norit C Granular (N2), Chemviron BPL-HA (N2), Chemviron ASC-TEDA (N2), an experimental activated carbon AC 147 (N2), a pitch-based activated carbon fibre (P3200-C02/900°C) manufactured at DSTL-Porton Down (N2), zeolite 13X14H (N2) and zeolite 13X12L (Ar). The last one was copied from the reference isotherms provided with the Mi-cromeritics ASAP 2010 poresizer that was used to measure the different isotherms. 

In summary, activated carbon fibres are produced, mainly, by the thermal activation of carbonized (and of course stabilized) carbon fibres. These carbon fibres may have been manufactured for purposes other than as an ACF precursor (like PAN based CF, mesophase pitch based CF) or specifically as a ACF precursor. For most CF precursors, the fibres are produced from direct melt spinning, resulting in the so-called green carbon fibres. These are...
