Porous carbon-based sorbents were synthesized from lignite coals of the Maikuben basin, specifically the Shoptykol deposit.The physicochemical characteristics of the produced materials were systematically investigated.A detailed material balance was calculated for both the carbonization and activation processes.Scanning Electron Microscopy (SEM) analysis revealed the formation of numerous carbon nanotubes (CNTs) with diameters ranging from approximately 69.5 to 200.2 nm
