【 摘 要 】

This work was aimed at investigating the influence of heating rate, particle size, pyrolysis time and temperature against the content of fixed carbon and characterizing the carbon black using Analysis of Variance (ANOVA). Pyrolysis technique conducted, employed an unstirred semi-batch reactor with capacity 1.150 L, which was equipped by a condenser and operated at 1 atmosphere as well as flowed by nitrogen gas at 1 L∙min-1. The tyre waste used as raw material was 30 g. The research variables used in this study were as follows: heating rate was 10-20 °C∙min-1 particle sizes were -10/+16 mesh, -16/+20 mesh, and -20/+30 mesh; pyrolysis time and temperature were 30-90 min, 400-600 °C, respectively. It was found that heating rate, particle size, pyrolysis time and temperature significantly affected with respect to the content of fixed carbon and carbon black characterization. The biggest content of fixed carbon was 61.8984 %, which was produced at heating rate of 20 °C; particle size was -20/+30 mesh conducted at 600 °C for 90 min. After performing an ANOVA analysis, the best carbon black obtained (iodine number 315.27 mg∙g-1, ash content 3.0983 %) was prepared at heating rate of 10 °C∙min-1, particle size -10/+16 mesh. Meanwhile, the highest moisture was obtained at heating rate of20 °C∙min-1, particle size -20/+30 mesh with similar pyrolysis time and temperature.
