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...
Activated carbons (ACs) were prepared in the presence of KOH at 400–800°C by carbonization of sugarcane molasses, a low-cost by-product of the vegetable sugar industry. All the ACs obtained were microporous materials. The AC that had the highest surface area (2202m 2 /g) was tested as a methane adsorbent at temperatures between 20 and 100°C. The adsorption data were modeled by Langmuir, Freundlich,...
