摘要

In preparing activated carbon by carbonizing and then activating cellulosic material impregnated with activating agent, the process of the invention is characterized by continuously supplying said activating agent-impregnated material into a carbonizing zone containing previously carbonized cellulosic material at such a constant flow rate as to allow the impregnated material to reside in the carbonizing zone at least for 15 minutes and carbonizing the impregnated material in said carbonizing zone with the carbonized cellulosic material which is heated at 150 DEG to 350 DEG C. by counter currently supplied hot gases and which forms an agitated fluidized bed by being fluidized with the hot gas stream and being stirred by a mechanical means.
