To control the production of carbonaceous materials with preset properties to be used as adsorbents, catalysts and fillers, carbonaceous materials (CM) are pre-activated. As a result, their functional properties are modified: porosity and specific surface area increase and the composition of functional groups changes. The authors have shown the results of the use of nonconventional modification methods, such as low temperature ozoning, the effect of the oxygen and inert plasma of a decaying charge, HF- and SHF-charges and ultrasound. Synthetic CM, such as carbonized and activated carbon fibres, polyacrylonitrile-based carbon ribbons, activated coals produced from sucrose, brown coal, coke and Karelian shungites. To interpret experimental results, the following methods were used: the kinetic
method, the adsorption method, the method for analysing acid groups on the surface, IR- and EPR-spectroscopy methods and X-ray electron microscopy.
