The lyophilic properties of pyrocarbon, obtained by pyrolysis of worn automobile tires, in relation to oil, gasoline, benzene, hexane, water, and water-oil and water-gasoline emulsions were studied. The research was carried out by the method of a lying drop on the surface formed by pyrocarbon particles of different dispersion, by determining the contact angle of wetting. The value of this angle was determined by analyzing images obtained photographically. It was established that organic substances and water have a significant contrast in terms of the wetting of pyrocarbon. Based on the determination of the contact angle, the work of adhesion in different systems was calculated depending on the temperature. Based on this, the conclusion was formulated that the selectivity of absorption of oil and oil products will increase with increasing temperature.
