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 N2 atmosphere. The highest liquid product yield was obtained at a pyrolysis temperature of 475o C for feed size of 4 cm3 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 475o C liquids showed that the tire-derived liquids are a complex mixture of C5–C16 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.
