Tire pyrolysis: Evolution of volatile and semivolatile compounds

The formation/decomposition of several compounds from the pyrolysis of tire wastes is compared in three different types of equipment. The types of lab oratory equipment consist of a Pyroprobe, where the secondary reactions are minimized, and a horizontal pyrolysis furnace, where the cracking is sever e. The yields obtained in both types of equipment are compared with those p reviously obtained in a fluidized bed reactor. On the other hand, the kinet ic severity function (KSF) has been proposed as a measure of the cracking u ndergone by the tars produced. This paper focuses on the production of semi volatiles from tire wastes.
