Abstract
A method and an apparatus using a fluidized bed type adsorbing tower for manufacturing a TEDA-impregnated active carbon which is used for removing toxic materials from a fluid. A base active carbon is dried to remove the water component, and the dried active carbon is filled into the fluidizing type adsorbing tower and to above a sieve plate. A TEDA reagent is injected into a TEDA vapor generating vessel. A heated air is supplied into the TEDA vapor generating vessel so as to generate a TEDA vapor mixed with the heated air. The heated air mixed with the TEDA vapor is supplied into the lower portion of the fluidized bed type adsorbing tower so as to make the base active carbon fluidized. Thus the TEDA vapor is impregnated into the active carbon within the fluidized carbon bed.
