Innovation in pyrolysis technology for management of scrap tire: a solution of energy and environment—Islam, 2010
In this research, a novel heating system for pyrolysis technology has been designed to recover liquid hydrocarbons from solid tire wastes. All of the process characteristics were taken into account during the design and construction of a fixed-bed fire-tube heating pyrolysis reactor system. In the reactor, solid tire wastes were pyrolyzed in a nitrogen gas atmosphere. The optimal pyrolysis conditions consisted of 475 degrees Celsius, a feed size of 4 cm3, and a vapor residence duration of 5 seconds, yielding the highest yield of liquid product. Fuel characteristics, elemental analysis, Fourier transform infrared spectroscopy, proton nuclear magnetic resonance, gas chromatography mass spectrometry, and distillation have all been used to characterize the liquids obtained from pyrolysis of tires. Because of their fuel qualities, pyrolytic liquids are being considered as alternatives to petroleum-based liquid fuels. The 475°C liquids were analyzed and revealed to be a complex mixture of C5-C16 organic molecules, including many high-value light hydrocarbons like limonene, as well as single-ring alkyl-aromatics and long-chain hydrocarbons. This study demonstrates a superior strategy for environmental and energy concerns.
