Activated carbon is a porous adsorbent. It is made from organic materials containing carbon.
Activated carbon can be produced from charcoal, peat (peat coke) or coal coke.
The Active-60 production line is designed to produce activated carbons of high adsorption capacity. Fields of application of activated carbons include the chemical, food, pharmaceutical, medical, fuel and energy, metallurgical, oil and gas extraction and processing industries, and also environmental protection. Filters containing activated carbon are used in many modern designs of devices for cleaning various media and materials (water, air, etc.). Read more: Use of activated carbon (Wikipedia)
The Active-60 unit can integrate into various designs of processing line. It can be used to activate or regenerate activated carbon, specifically:
A key feature of the ACTIVE-60 activation installation is the use of SynGas, a combustible synthesis gas (read more about SynGas) released during the activation process, to drive key process reactions: coal heating, steam production and superheating. That allows you to save big money on energy - the use of additional fuel is not required.
The process of pyrolysis – the carbonization of raw materials - can be included directly in the technical activation line, or a stand-alone line can be used for activation of "finished" coals.

The components of the ACTIVE-60 installation
|1||Activation kiln||Rotary kiln with refractory brick lining. Comprises a receiving unit, a rotating drum and a finished activated carbon unit|
|2||Burner||Gas or oil burner for initial start-up of the furnace. When using a liquid fuel burner, the consumption of heating oil for primary heating is 150-200 l / h, the time for heating is 8-10 hours.|
|3||Loading unit||Storage hopper and closed auger with period control. Used to load raw materials into the kiln|
|4||Unloading unit||Gateway feeder and closed auger with steam cooling. Used for unloading and cooling the produced carbon|
|5||Water Treatment Unit||Used to prepare water for the steam production process. Prevents the formation of scale on the steam pipes and so avoids frequent cleaning of steam pipes.|
|6||Kiln steam supply unit||Used to supply superheated steam to the oven. Equipped with a pressure gauge to monitor the pressure in the system. Made of acid resistant stainless steel|
|7||Steam boiler with superheater||Low pressure steam boiler, with superheater. Not subject to high-pressure steam regulations. As a heat source, the gas released as a result of the activation reaction is used.|
|8||Flues, chimney, smoke exhaust fan||Flues - pipes for gas and coolant. Chimney - 20 mPa. Smoke exhaust fan 2.2kW|

Brief description of the ACTIVE-60 installation
The rotary kiln is a continuous apparatus for heat treatment and activation of various bulk materials and materials with a high porosity. The design of the installation involves the use of synthesis gas released in the process, for heating the raw material to the activation temperature and in the production and superheating of steam for activation. At initial start-up the unit is heated by liquid or gaseous fuel. The inner housing of the drum is lined with refractory brick. Prepared raw materials are loaded into the installation where it is heated to a temperature of 900 ° C, superheated steam is supplied to the heated raw material at a temperature > 350 ° C. As a result of the reaction, activated carbon and synthesis gas are obtained. The resulting activated carbon from a rotary kiln flows into the active carbon cooling zone, from where it is in turn discharged through a lock discharge device.
