pyrocarbon

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.

The paper describes the results of studying the composition and properties of pyrocarbon obtained during the pyrolysis of rubber waste. The ability of pyrocarbon to absorb oil and oil products was determined using four developed methods. It has been established that pyrocarbon can find practical use as an adsorbent for the collection and localization of spills of oil and oil products on solid and water surfaces.
