Activation of tyre pyrolysis char (TPC) can significantly increase its market value. To date, it has been frequently carried out in different reactors. In this work, thermogravimetric analysis was used instead. The performance of activated pyrolysis chars was tested by adsorption of acetone vapour and comparison of the equilibrium adsorption capacities for all samples. The highest equilibrium adsorption capacity was observed for the carbon burn-off of 60%. In addition, the equilibrium adsorption capacity of activated TPC decreases by about 10% after eleven adsorption/desorption cycles. Moreover, activation changed the porous structure of pyrolysis chars from mesoporous to micro-mesoporous.
