Innovation in Pyrolysis Technology for Management of Scrap Tire: a Solution of Energyand Environment

Abstract

In this study a new approach in heating system for pyrolysis technology to the recovery of liquid hydrocarbons from solid tire wastes has been developed. A fixed-bed fire-tube heating pyrolysis reactor system has been designed and fabricated considering all of the process parameters. The solid tire wastes were pyrolysed in the reactor under N 2 atmosphere. The highest liquid product yield was obtained at a pyrolysis temperature of 475 o C for feed size of 4 cm 3 and vapor residence time of 5 sec. The tire pyrolysis liquids have been characterized including fuel properties, elemental analysis, FT-IR, 1 H-NMR, GC-MS analysis and distillation. The fuel properties of the pyrolytic liquids encourage their use as replacements for conventional liquid fuels. The analytical results of the 475 o C liquids showed that the tire-derived liquids are a complex mixture of C 5 -C 16 organic compounds, with a lot of high value light hydrocarbon limonene, single ring alkyl-aromatics and long-chain hydrocarbons. The present research result shows a better solution for energy and environment.
