Inexpensive pyrolysis char from spent tyres is a promising precursor to produce activated carbon, offering unique advantages due to high Zn content. This thesis investigated the production of ZnO-enriched activated carbon, focusing on the effect of activation conditions on the product yield and properties, CO2 gasification kinetics, and the fate and transformation of Zn during activation. It was found that the CO2 gasification of the char is kinetically controlled, which is also catalysed by Zn present in the char. However, a trade-off between the optimum surface properties and Zn retention in the activated carbon product was observed.
