Abstract

The most important raw material component in the production of most types of carbon products is binding materials, the quality of which largely determines the physical and mechanical properties of the product. A favorable combination of high coke ability and low viscosity in the molten state distinguishes pitch from other types of binding materials for various carbonaceous compositions subjected to subsequent carbonization. For this reason, pitch worldwide is a priority binder for many types of carbon products (anode masses, electrodes, structural materials, electrical products, etc.). The advantages and shortcoming of available materials for the production of anode mass in detail. The known and novel methods for obtaining oil binders were analyzed. The obtained binders compared with coal tar pitch. An alternative method for production of the binders via the compounding technique was proposed. Implementation of this technology allow replacing the coal tar pitch containing a significant amount of 3,4 benz [a] pyrene by a carcinogen petroleum pitch. Coal pitches have a high carcinogenic activity due to the high content of 3,4-benz [a] pyrenes and other (up to 4%) polyaromatic hydrocarbons, impurities (F, Fe, Co, V, W, etc.) and ash. In addition, such pitches technological characteristics (from different manufacturers) and high cost. The imperfection of production technology, the considerable remoteness of production from consumers and, as a consequence, high transportation costs allow considering the off-market materials
