Obtaining activated carbon from wood waste

Purpose. To create a technology for producing activated carbon from wood waste instead of traditional fossil raw materials (coal) with competitive adsorption characteristics to reduce the cost of sorbents when extracting inorganic and organic compounds of typical water pollutants from water bodies.

Specifications. Drying the source material at 30-83 degrees. C. Carrying out the pyrolysis process at a temperature of 605-745 degrees. C

Application area. Water treatment and treatment

Advantages. Traditional pyrolysis technology has been modernized by using wet cooling, which causes the activation of heated carbonized material and ensures additional development of the cellular structure of AB from wood waste.

Technical and economic effect. Replacing fossil raw materials (coal) with wood or agricultural waste will reduce the cost of production by 1.5-2 times and lead to a reduction in greenhouse gas emissions. The production and use of DBW will lead to an improvement in the ecological state of the environment at the local and national level and will entail an expansion of the functional use of activated carbonized products not only in the field of natural and wastewater treatment, but also to improve the quality and fertility of soils, increase agricultural productivity and etc.

Description. The production of activated carbon from wood production waste was carried out in an industrial pyrolysis installation after obtaining the coolant and drying the source material at (30-83) degrees C, which was converted into wood biochar in the pyrolysis unit at a temperature of (605-745) degrees C, followed by wet cooling, in which cooling, activation and, as a result, further development of the porous structure of activated carbon simultaneously occur.
