Abstract
Carbon fibres can be produced from a variety of precursor materials including rayon, polyacrylonitrile (PAN) and pitch materials. When there carbon fibres are activated, it is possible to produce a material with low hydrodynamic resistence which may be used as an adsorbent for treatment of high gas flows. Elimination of the channelling and settling which often occurs with powdered or granular carbons can be achieved with the selection of textile form (woven, nonwoven etc.). The raw material dictates the price of the final product. Fibres produced from the cheaper cellulosic raw materials were often the fibre of choice for many of the initial research investigations and applications. Later pitch-based fibres became the focus of many studies.
