Waste tire-based pyrolysis for synthetic fuel and study of its properties

Thermal pyrolysis of waste tires is an economically viable industrial method for material recovery and energy production. This article presents the results of research on the processing of used car tires by the pyrolysis method in a nitrogen-free environment under atmospheric pressure. Tires sourced from a local vulcanization center were used as raw material. The pyrolysis process was conducted using an experimental setup consisting of a pyrolysis reactor, a collector for gases and liquids, and a condenser. For the experiment, 4180 g of tire fragments were used. The process was carried out at a temperature of 500°C and atmospheric pressure for one hour. As a result, 1800 ml of pyrolysis oil, 1320 g of carbon black, 600 g of metallic cord, and 630 g of pyrolysis gas were obtained. The physical properties of the pyrolysis oil were studied: the density was 0.906 kg/m3, the kinematic viscosity was 0.75 mm2/s, and the acidity was 104.4 mg/dm3. Infrared spectroscopy analysis of the oil revealed the presence of aromatic, alkene, and alkyne groups. Liquid fuel was obtained from the pyrolysis oil using a distillation unit. From 150 ml of pyrolysis oil, 60 ml of liquid fuel was produced. Elemental analysis indicated that the pyrolysis oil contained nitrogen (2.57%) and sulfur (1.27%).
