Development of fluidized-bed pyrolysis of waste tires

Kinetic Modeling of Scrap Tire Pyrolysis

“…Several power plants using waste tires as the primary fuel have been commissioned in Europe and the United States . Gasification is the process of converting tire into a mixture of combustible gases with the use of air, oxygen, or steam. , Tire pyrolysis is an incomplete thermal degradation process, generally conducted in the absence of air, which results in liquid and gaseous hydrocarbons and char residual. − These products can be converted for different uses. For instance, the char can be converted to carbon black or activated carbon, − which are widely used chemical products.…”

Numerical model for the vacuum pyrolysis of scrap tires in batch reactors

“…This approach, which has been under development over the last twenty years, is based on the air-free thermal decomposition of tires at high temperature (450-800°C) to useful products such as carbon black, pyrolysis oils, steel and gas. Several pyrolysis processes have been proposed, such as vacuum pyrolysis (Roy et al, 1989(Roy et al, , 1990, flash pyrolysis (Che et al 19761, molten salt pyrolysis (Chambers et al, 19841, and a few batch processes (Araki et al, 1979;Bouvier et al, 1987;Schulman and White, 1978;William et al, 1990). The published literature deals primarily with process description, product characterization, and market surveys.…”

Tire Waste as a Potential Material for Carbon Electrode Fabrication: A Review

“…Deeper comprehensive description of the pyrolysis process and characteristics that implemented in the country that mention above can be seen elsewhere [23,24,25,26,27,28]. From an industrial point of view, several authors [26,27,29] pointed out that pyrolysis of tire waste was first attempted in the early 1970s by the US Bureau of Mines collaborating with the Firestone Company in the United State. 10 tires per day at laboratory unit and produced 3.8 l of liquid, 1.4 kg of gas, 3.2 kg of char and 1 kg of steel and char for every tire pyrolysis processed [26].…”
