The determination of the sorption properties of peat from different depths was done. The research was carried out on the intermediate littoral peats near the Baltic Sea from the layers situated at every 0.5 m at depths up to 3 m . The effectiveness of peat sorbents has been detd. based on the isotherms of SO2, benzene, and CO2 sorption. This was done using the gravimetric method. The interpretation of the benzene sorption isotherms was carried out on the basis of the theory of volumetric filling of pores. These results were compared with respectively investigations on samples of steam-activated carbons (based on hard coal and wood tar) and demineralized brown coal.

Shungite rocks were investigated as possible adsorbents and catalyst for ozone removal and use in coal liquefaction. It was shown that the shungite action is based on shungite carbon properties. Shungites may be used successfully for ozone removal after water treatment and then as additives in coal liquefaction.

Earthy brown coal, its humic acids, and their derivs. were investigated in coal ozonation and liquefaction. Ozonation was used for coal modification to liquefy coals and to produce possible adsorbents and catalysts.

Natural fullerene like and polyaromatic substances and synthetic fullerene C 60 had catalytic in coal treatment. Synthetic fullerene C 60 and shungite carbons from two deposits of Karelia, Russia, accelerated benzyl phenyl ether thermolysis without the process character changing, but they changed tetralin thermolysis: the main reaction was the dehydrogenation teralin into naphthalene. Dehydrogenation led to rapid conversion of COM into defferent aromatic compounds such as naphthalene, phenathrene, benz[a]pirene and so on even at low temperatures. Catalytic ability of shungite carbons in different organic reactions was supposed to be due to its fullerene like structure.
