Design and Manufacturing of Test Rig for Pyrolysis of Waste Tyres of Two-Wheeler Vehicles (ELVs)

Abstract

The automobile industry works as a pillar in the manufacturing sector in a developing country like India. Due to a huge number of vehicles on the verge of the end-of-life, guidelines for the management of it came in existence with a law, AIS132, a couple of years back. This research has focused on environment-friendly methods for tyre recycling in the automobile industry. In pyrolysis process, the tyre is heated to 500–600 °C in the absence of oxygen, which leads to thermal cracking of waste tyres, and the output of this process was oil after condensing of the evolved gases. The properties which were considered to compare with diesel properties were cetane number, flashpoint, pour point, viscosity at 40 °C, calorific value, carbon content, sulphur content and density. Results of the study show that tyre pyrolysis liquid generated during the process has the properties like that of diesel. Hence, the generated liquid can be blended with diesel and this increases the commercial value of waste tyres and further helps in alleviating the ELV problem.
