Energy recovery from waste tires by processes such as incineration, pyrolysis and gasification is one of the most widely used and best management options for these materials in the world. Pyrolysis is one of the ways in which in addition to recycling polymer waste and minimizing the environmental problems caused by these wastes, chemical precious materials can be produced or used as additives to other precious materials. Pyrolysis is a thermal, non-combustion process that decomposes by heating the material in an oxygen-free environment. Using pyrolysis of used tire, volatile gas products, pyrolysis oil and residual solid are obtained from decomposed tire. In the rotary reactor, the decomposition temperature for pyrolysis tires is up to 1100C. For the production of heavy pyrolysis oil, the reaction temperature was set at 300-550 ° C. At 430 ° C, the maximum oil yield was 42.17 wt% for truck tire and 45.48% wt for passenger tire. At low temperatures, heavy oil obtained by pyrolysis can be used as an additive to bitumen to improve some of the bitumen's properties, including the penetration, which does not require further aeration for the production of bitumen. In addition, the FCC catalyst at 430 ° C, which produces the most pyrolysis oil, was used to further decompose the tire. With this catalyst, the production of liquid and solid products is reduced and the gas evaporates more. That is, at this temperature, the liquid product rate of 45.48 for car tire is reduced to 37wt% and the residual solid content of pyrolysis is reduced from 41% to 38% by the catalyst due to the reduction of solid residue from rubber pyrolysis. It is environmentally friendly, while the volatile gas product volume increases from 14 to 25 %wt.
