feature:1.narrow micro-aperture.2.stronger adsorb role 3.easily regenerated. The activated carbon fiber felt,which adopt the natural fiber and man-made fiber non-woven felt,be made by carbonize and activation.it has large specific surface area ,900-2200gm2/g,and has developed micro-aperture,the adsorption speed is 10-100 times than granule activated carbon. benzene adsorption value is 580 mg/g, ...
