Applications for activated carbons from used tires: butane working capacity Original Research Article

Activated carbons obtained from the pyrolysis (600–800°C) of used tires have been synthesized and studied for n-butane adsorption. To obtain optimal butane working capacity (BWC), higher burn-off was found necessary. It was also found that higher pyrolysis temperatures (∼800°C) allow mesoporosity to develop more readily and furthermore this porosity leads to higher BWC.
