Abstract
Proximate analysis was carried out to determine the moisture, volatile, fixed carbon and ash content of Carbon Black derived from waste tyre thermal treatment. The procedure used followed the British Standards for the proximate analysis of coal. From the proximate analysis, it was determined that 8% and 10% of the Carbon Black were moisture and volatile matter. To remove the moisture and volatiles from the Carbon Black, treatment with air at elevated temperatures was recommended. Thermo-gravimetric analysis (TGA) of the Carbon Black was then carried out at 450°C, 500°C and 600°C. The results of the TGA showed that treatment at 450°C would require a long treatment time to remove the volatiles from the Carbon Black while treatments at both 500°C and 600°C were effective in removing the volatiles. However, with weight losses of 23.7% and 35.2% respectively for 30 and 60 minutes, treatments at 600°C were shown to be most effective in removing all the volatiles. Once the residual volatiles have been removed from the Carbon Black, further activation treatment was carried out in air at 850°C and CO2 at 850°C and 900°C to enhance its surface area and potential application as adsorbents for waste removal from fluid streams.
