Abstract: The low-temperature pyrolysis of the scrap tire was investigated by Fisher assay test and thermogravimetric test. Results showed that the main products were pyrolysis oil and carbon black with yield of 52.7% and 38.0%, respectively. The pyrolytic gas can meet the thermal energy demand of pyrolysis process without external fuel. The tire pyrolysis can be fully finished at 500℃, but takes longer time, about 180 min. Thus, it needs to improve pyrolysis process to enhance the equipment efficiency.

Key words: waste tire, pyrolysis oil, carbon black
