Abstract

This PhD thesis reports a systematic investigation into carbon black (CB) preparation from spent tyre pyrolysis oil (STPO) and heavy residue fraction (HRF) via high-temperature partial oxidation. It is shown that the CB quality increases with increasing temperature, residence time and oxygen to feed ratio at the expense of the yield, suggesting a trade-off in choosing appropriate process variables. An upgrade of the CBs via controlled air oxidation resulted in the formation of hollow carbon nanospheres. This research lays a sound scientific foundation for the development of future processing technology for converting similar waste feedstocks into valuable carbon products.
