An advanced method of adsorbent surface analysis\u2014more specifically, the new method of numerical clustering-based adsorption analysis regarding the surface heterogeneity, pore geometry and adsorption energy distribution parameters\u2014allowed us to obtain information about the porous structure of the ACs from the synthetic polymers mentioned above. As the results showed, ACs obtained with PAN were characterised by a first adsorbed layer with the highest volume. When the surface heterogeneity, highly desirable in most advanced adsorption processes, is taken into account, the materials with the best surface properties in both potassium carbonate (K2CO3) and potassium hydroxide (KOH) activation processes were the ACs obtained with a mass proportion of PET to PAN of 1:3, which were characterised by a low degree of surface heterogeneity and a first adsorbed layer presenting a relatively large volume.<\/jats:p>","DOI":"10.3390\/ma17133122","type":"journal-article","created":{"date-parts":[[2024,6,26]],"date-time":"2024-06-26T07:20:06Z","timestamp":1719386406000},"page":"3122","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Numerical Analysis of the Porous Structure of Activated Carbons Derived from Synthetic Polymers"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9644-6530","authenticated-orcid":false,"given":"Miros\u0142aw","family":"Kwiatkowski","sequence":"first","affiliation":[{"name":"Faculty of Energy and Fuels, AGH University of Krakow, al.
