Activation and adsorption of ACF needle felt

Dongsheng Chen, Gan Ying-jin, Hongwei Zhang

Abstract

A needle felt was produced with the blend of polyacrylonitrile(PAN) and viscose fibers.Then,the needle felt was pre-oxidized in the air at 230~(250 ℃),followed by carbonizing and activating by one-step process.A detailed research was conducted on the technologies of production,pre-oxidization,and one step carbonization-activation of the needle felt.Its pre-oxidization extent was expressed with the moisture content.The iodine adsorption capacity and yield of the activated carbon fiber(ACF) needle felt were also studied.
