    The adsorption properties of microporous spherical carbon materials obtained from the resorcinol-formaldehyde resin, treated in a solvothermal reactor heated with microwaves and then subjected to carbonization, are presented. The potassium-based activation of carbon spheres was carried out in two ways: solution-based and solid-based methods. The effect of various factors, such as chemical agent selection, chemical activating agent content, and the temperature or time of activation, was investigated. The influence of microwave treatment on the adsorption properties was also investigated and described. The adsorption performance of carbon spheres was evaluated in detail by examining CO2 adsorption from the gas phase.

    Microporous spherical carbon materials were obtained from the resorcinol–formaldehyde resin, treated in a solvothermal reactor heated with microwaves, and then subjected to carbonization. The effect of the pH on the changes in the carbon spheres' morphology and the adsorption performance was investigated. In order to improve the adsorption efficiency, carbon spheres were subjected to the activation using potassium hydroxide and their properties were compared to those of the non-activated ones. The adsorption performance of the produced materials was evaluated in detail by examining nitrogen and carbon dioxide adsorption from the gas phase, the morphology – using Scanning Electron Microscopy, and surface chemistry – using X-ray Photoelectron Spectroscopy.
