PURPOSE: A method for fabricating a porous fiber phase carbon material is provided to improve strength and to obtain the carbon material which is applicable as an adsorbent. CONSTITUTION: A method for fabricating a porous fiber phase carbon material comprises: a step of pre-treating a natural fiber with 1-50% of a sodium hydroxide(NaOH) solution for a predetermined time(S10); a step of washing and drying the pre-treated natural fiber(S30); a step of stabilizing the natural fiber at 200-350 Deg. C. for 10 minutes to 5 hours(S30); a step of carbonizing the natural fiber at 500-1200 Deg. C. for 1 minute to 5 hours(S40); and a step of activating the carbonized natural fiber at 500-1200 Deg. C. for 1 minute to 10 hours(S50). The natural fiber includes kenaf, jute, bamboo fiber, coir fiber, or rice straw fiber.
