Draft SoP on “Recycling of Waste Tyre Scrap for the production of Tyre Pyrolysis Oil in Tyre Pyrolysis Oil (TPO) Units
Background
Pyrolysis is a thermal degradation process carried out in the absence of oxygen/air in a vessel or a chamber so that the combustion of material does not take place. It is a process in which organic materials are thermally decomposed into simpler compounds in the temperature range of 400–5000 C in an oxygen-free atmosphere. Fig. 1 shows the schematic diagram of waste tyre pyrolysis process. Since the products of thermal decomposition is released at different temperature having varying molecular structure, the products are in all phases i.e. solid, liquid and gas. Pyrolysis of tyres and rubber products produce pyrolysis oils, pyrolysis gas (pyro- gas), carbon residue and steel. The product generated in tyre pyrolysis is as follows:
