Abstract

The article presents the results of experimental studies on the yield and properties of pyrolysis liquid, solid carbon-containing residue and the composition of gaseous substances as a result of thermal decomposition of rubber waste in a cylindrical reactor with a fixed dense layer with a heating rate of 10–12 °C and exposure at process temperatures of 550, 600, 650 and 700 °C. The material balances of the pyrolysis process of rubber chips from used large- size tires of size classes 0–1, 1–3, 2–3.5 and 2–4 mm have been compiled. The volumes of the products obtained and the rate of formation are shown depending on the exposure time of the pyrolysis process. The results of numerical simulation of the thermal decomposition process in a cylindrical reactor with a fixed dense layer for crushed spent large tires with a size of 1–3 mm in the temperature range from 350–370 (the beginning of the release of volatile substances) to 700 °C in terms of the composition of the gas phase and solid residue at a temperature of 550 °C are presented
