The pyrolysis method presents the possibility of transforming hundreds of tons waste tires into gaseous, liquid, and carbon-rich solid (RCB) fractions, mainly contains carbon fractions from conventional carbon black (CB) and inorganic ingredients used during tire building.
All three products including pyrolytic carbon black (CBp), tire pyrolysis oil (TPO) and pyrolysis gas showed good characteristics. Pyrolysis gas had been successfully re-used for pyrolysis furnaces and dryers. The higher heating value of TPO estimated to 37-40 MJ/ kg, which was comparable to diesel fuel through further treatment.
products, also referred to as carbon black (v). It is commonly used in black -colored day-to-day use products such as car tires. Its substitute, recovered carbon black (r), produced via thermal pyrolysis, addresses two opportunities. First, it provides a sustainable way of recycling used tires from which r is derived .
The process also reduces the tires to synthetic gas, recovered carbon black and tire pyrolysis oil. Orion is the only company that has made circular carbon black from tire pyrolysis oil as a feedstock. The company has also demonstrated that its circular products can replace carbon black in many applications. Alpha …
