DEPENDENCE OF POLYCYCLIC AROMATIC HYDROCARBONS (PAHS) RELEASE ON SULFONOL IN THE PROCESS OF PRODUCING TU-5 CARBON BLACK

In recent years, the use of technical carbon in the electrical engineering field has also been expanding. Studies have shown that the electrical conductivity of technical carbon depends on its particle structure and degree of aggregation. In particular, technical carbon with a high surface area (BET 500–900 m²/g) can be used in electrodes in supercapacitors and lithium-ion batteries. Electrode materials based on technical carbon have high charge-discharge cycle stability [3-4]. Technical carbon is of great importance. In addition, technical carbon is used as a carrier material in catalytic systems. Studies have shown that chemical modification of the carbon surface improves catalyst dispersion. This leads to an increase in active centers in chemical reactions. It has also been found that technical carbon-based catalysts are highly effective in biofuel production [5-6]. Technical carbon is widely used as a black coloring material in the pigment and paint industry. According to their studies, the optical properties of technical carbon are related to particle size and surface structure. Fine-grained technical carbon provides high black intensity [7]. Technical carbon also has high prospects for use in environmental areas [8].
