Abstract:
The paper studied adsorption characteristics of carbon sorbents produced from naturally oxidised coal of Barzas deposit. Synthesis of sorbents was carried out by the chemical activation method using potassium or sodium hydroxide and carbonization at 800 °С. The effect of alkaline nature and the amount of the introduced alkali at the impregnation stage on characteristics of the resulting sorbents was studied. Adsorption characteristics were explored on an example of benzene, phenol, and iodine. Benzene adsorption under the studied conditions linearly depends on the total pore volume in the sorbent. It was demonstrated that sorbents produced from the naturally oxidised Barzas coal activated by potassium hydroxide had the developed porous structure and high adsorption characteristics. To produce sorbents with high characteristics from the naturally oxidised Barzas coal with potassium hydroxide activation it was sufficient to use a coal/KOH mass ratio of 1 : 0.5.
