Abstract: A method of production of active carbon by pyrolysis of organic materials, includes pyrolysis unit, reforming unit, drying unit, purification unit, gas storage unit and high temperature regenerative combustion unit. Organic materials are subjected to pyrolysis reaction in pyrolysis unit to produce combustible gas, tar and char. Combustible gas is reformed through reforming unit then enters into the drying unit for drying organic materials. One part of the purified combustible gas is combusted in the direction of combustion channel in the high temperature regenerative combustion unit, and the combustion heat is produced. At the same time, another part of combustible gas exchanges heat in the direction of heat exchanger channel in the regenerative combustion unit. Then it is used as pyrolysis activation medium entering into the pyrolysis unit in process of pyrolysis and activation reaction. The char is activated by the combustible gas in the pyrolysis unit then forms activated carbon.
