| Abstract Scope |
Carbon black is a reinforcing filler used in car, truck, and mining equipment tires (~30 wt.%) and is made by the partial combustion or petroleum products. One management strategy for waste tires is pyrolysis, where the products are: high carbon steel, two grades of fuel, and carbon black. The steel requires no treatment post processing for recycling, while the fuel generated is used to heat and power the process. The remaining carbon black is contaminated by various additives in the original tire, as well as contaminates produced during pyrolysis. The presence of such contaminates on the surface and in the bulk of the carbon particles affects the fundamental characteristics of the virgin carbon black. As a result, the produced carbon black cannot be re-used directly and requires treatment to upgrade the purity. This work will discuss possible purification strategies of pyrolyzed carbon black and the associated embedded energy. |
