This project illustrates the production method to convert activated carbon from waste tyre char under steam activation. Tyre char activated carbon by different parameters, activation temperatures (900, 925, 950 and 975 deg-C) and residence times (2, 4 and 6 hours), were produced and then characterized.

This project illustrates the production method to convert activated carbon from waste tyre char under steam activation. Tyre char activated carbon by different parameters, activation temperatures (900, 925, 950 and 975 deg-C) and residence times (2, 4 and 6 hours), were produced and then characterized. Calgon Carbon, F400, is used for a reference carbon.

One activated carbon produced at 975 deg-C for 6 hours is 975-6. It is a mesoporous carbon with nearly 94.7% of its pores being mesopores. Although its impurities contents are high when comparing with F400, it has a similar BET surface area and higher total pore volume.

It is considered that the methylene blue adsorption capacity and iodine number of 975-6 are comparable with F400, which are 1.37 mmol / g and 846.9 mg / g , respectively.

It is believed that it is feasible to use tyre char activated carbon as an adsorbent to remove large molecules, such as, dye molecules in industrial wastewater, due to the mesoporous properties.
