Microwave activation technology of electro-spun PAN fibers and their adsorptivity

This paper introduced the electro-spinning of PAN fibers,equipments and methods for microwave activation of electro-spun PAN fibers.The effect of PAN content on electro-spun PAN fibers and the relationship between activation yield,adsorbent efficiency of benzene and activation time were researched.And a comparison was made of activation yield and adsorbent efficiency of benzene between the conventional PAN-based activated carbon fibers,rayon-based activated carbon fibers and electro-spun PAN fibers.It is considered that the activated carbon fibers with more activation yield and better adsorptivity can be obtained by means of electro-spun PAN fibers.
