The paper presents the results of research into the effects of the additional activation process of the commercial activated carbon WG-12 with KOH, ZnCl2, KOH/ZnCl2 and K2CO3 as activating agents on the formation of the porous structure and the adsorptive properties of that material. The numerical analyses were carried out on the basis of the isotherms of nitrogen adsorption with the use of the method based on the Brunauer-Emmett-Teller, the Dubinin-Radushkevich equations, the non-local and the quenched solid density functional theories as well as the LBET method with the unique fast multivariate procedure of porous structure identification and the new LBET class adsorption models. Also, the research in question yielded information regarding the usefulness of the said methods of carbonaceous adsorbent porous structure description for practical technological applications and scientific research, as well as the possibilities to make practical use of the research results.
