The paper describes the results of studies on the thermally oxygen-free decomposition of the polymer components of a car tire during its direct immersion into the molten liquid metal. The influence of the conditions of liquid metal pyrolysis of used automobile tires on the composition and form of the products obtained was studied. It is shown that the proposed processing technology not only effectively disposes of accumulated waste, but also useful to use the products obtained (such as: solid in the form of steel cord and coal-like mass, pyrolysis fluid and non-condensable pyrolysis gases) with the possibility of commercial gain. The dependences of the content of the liquid components in the pyrolysis liquid on the temperature of the process are revealed. It was revealed that pyrolysis liquid contains up to 30 % of gasoline fractions (with a boiling point of up to 180 °C), up to 40 % of kerosene fractions (with a boiling point of from 180 to 315 °C) and from 30 to 50 % of heavy oil products regardless of the method of pyrolysis The dependencies of the composition of the obtained gaseous products on the temperature of the process are revealed. According to the results of the analysis of the fractional composition of liquid and gaseous products, the optimum temperature regime for the process of pyrolysis of used automobile tires was chosen, which is located in the range of 430±20 °С.
