Different approaches to the variation of the porous structure of industrial activated carbon Aquacarb with given morphology and parameters of the porous structure are considered and represent an alternative to the conventional methods for the development of the porous structure of coals. Due to the physical and combined activation of microporous coal Aquacarb, samples with a developed mesoporous component are obtained. The effectiveness of approved technological approaches is proven. The most effective activation methods are a physical activation by means of the steam–air activator (SBET???2265 m2/g, Sme???378 m2/g) and a combined activation involving the initial chemical activation of H3PO4 followed by activation with a vapour–air mixture (SBET???2444 m2/g, Sme???438 m2/g).
Keywords: industrial microporous carbon Aquacarb, physical activation, combined activation, surface area, porous structure, sorptive properties, methylene blue
