Characteristics of the reactants and products, the process conditions, and the yields of pyrolytic products are based on an extensive literature review and on the data collected in the laboratory. The primary products of tire pyrolysis are pyrolytic gas (also known as pyro gas), oils, banded steel and char. This process yields substantial quantities of oils and char, which can undergo additional processing to secondary, value-added products. According to the proposed scheme, char upgrading is implemented in a closed-loop activation step that yields an activated carbon and eliminates undesirable byproducts and emissions.  A stream of C02  is used for high-temperature char activation, which is followed by C02 recovery through the reverse Boudouard reaction. The latter step is an optional feature of the proposed process. Upgrading the char produces high ­surface-area activated carbon and finely divided carbon, which we refer to as the Boudouard carbon. Ash-free oils are turned into high-quality carbon black by using the furnace process.
