PREPARATION METHOD OF LIGNOCELLULOSE BASED ACTIVATED CARBON

摘要

PURPOSE: A preparation method of lignocellulose based activated carbon is provided to prepare activated carbon having high density and high performance by a simpler preparation process compared to an existing preparation process. CONSTITUTION: The preparation method comprises processes of mixing lignocellulose, chemical activating agent and water; thermosetting the mixture; pulverizing the thermosetted mixture; adding molding supporting agent to the pulverized material; cohering the molding supporting agent added material; forming the cohered material into a high density pellet shaped thermosetting powder using an injector, and chamfering cohered material at the same time; drying the chamfered thermosetting powder at a temperature of 120 to 150 deg.C for 1 to 2 hours; activating the dried material to a temperature of 400 to 600 deg.C in a furnace; cleaning the residual chemical activating agent using water; and drying the water cleaned residual chemical activating agent, wherein mixing, thermosetting, pulverizing, molding supporting agent adding and cohering processes of the lignocellulose, chemical activating agent and water are performed in a lump in a high shearing force mixer to which a heating source is attached.
