Abstract
PURPOSE: To obtain a fibrous active carbon of high performance, by the activation at a high temperature in a short time, by oxidizing acrylic fibers containing a P compound and/or B compound under specific conditions, additionally applying the P compound an/or B compound thereto, reoxidizing the resultant fibers, adjusting the contents of P and/or B to a specific value, and activating the fibers at a specified temperature.
CONSTITUTION: Acrylic fibers containing 0.01W0.3wt%, expressed in terms of P and/or B, P compound and/or B compound are oxidized in an oxidizing atmosphere at 200W400°C to give a combined oxygen content of 5W8%, and 0.02W 0.3wt%, expressed in terms of P and/or B, P compound or B compound or both are additionally applied thereto. The resultant fibers are then oxidized at 250W 400°C, preferably in an inert gas with an oxygen content of 0.2W9vol%, to give a combined oxygen content ≥15% and a core ratio ≤8%. P compound or B compound or both are added if necessary to adjust the P and/or B contents to 0.04W1wt%, and the fibers are activated at 900W1,300°C.
