PROCESS FOR PRODUCING COARSE PARTICLES OF ACTIVE CARBON IN A FLUIDIZED BED WITH ADDED INERT PARTICLES

摘要

Process for producing coarse particles of active carbon having an average particle size of 2 to 20 mm by means of a fluidized bed in a reactor in which particles of carbon or carbonaceous material are mixed with a finely powdered inert material having a preferable particle size of 0.08 to 1.0 mm and caused to move upward at low speed by passing a high temperature gas containing steam through the mixture forming the fluidized bed, thereby to obtain activation of the carbonization of the carbon particles with good effect.
