In Taiwan, the annual generation of scrap tire is over 100,000 tons.  Therefore, its recycling system is a typical circular economy because it is a mandatory waste by the EPA.  Carbon black may be an earliest used nanomaterial, which has been mainly added to rubber-based products (e.g., tire) as a reinforcing agent due to its non-crystalline agglomerate.  In this technology, a proper pretreatment was applied to remove some residues (i.e., ash) in the recycled carbon black from the scrap tire pyrolysis process.  Moreover, the physical characterization (e.g., specific surface area) of the de-ashed carbon black was further upgraded by using a thermal activation.  Under the experimental conditions investigated, the ash content significantly decreased from 14 to below 5 wt%.  Furthermore, the BET surface area increased from ca.70 to over 450 m2/g.  The thermally activated carbon black can be used as adsorbent, bio-support, catalyst support, or new energy and carbon materials.

碳黑已是一高熱安定性之碳材料，故欲改變其物理特性(如增加比表面積)相當不易。
