Tire pyrolysis specifications

tyres pyrolysis plant news / DATE:2014-11-18

Pyrolysis way for recycling scrap tyre is a technique which heats whole or shredded tyres in a reactor vessel containing an oxygen free atmosphere and fuel.

In the reactor the waste tyres/plastic is softened when the pyrolysis plant heated to high temperature after which the waste polymers continuously breakdown into smaller molecules.

These smaller molecules eventually vaporize and exit from the reactor.

These vapors can be burned directly to produce power or condensed into an oily type liquid generally used as a fuel. The fuel can be used as heating material, in glass factory, in cement factory, steel factory.

Some molecules are too small to condense. They remain a gas which can be burned as a fuel. The oil gas which cannot be condensed will be recycled to heat reactor instead of fuel. Thus will save much energy.

The minerals that were part of the tyre, about 40-45% by weight, are removed as a solid.

When performed well a tyre pyrolysis process is very clean operation and has nearly no emissions or waste. This means the pyrolysis plant is environmental friendly it will generate no pollution to the environment.

The properties of the gas, liquid and solid output are determined by type of feed stock used and the process conditions. The liquid oil has a fuel value 60%-70% compared with petroleum based crude oil.

What is more, whole tyres contain fibers and steel, shredded tyres have most of steel and sometimes most of the fiber removed.

The steel can be removed from the solid stream with magnets for recycling. The remaining solid material referred to as “charcoal”.

 final product of tire pyrolysis:

Fuel oil

carbon black

oil gas

steel wire

oil yield rate is about 42%-52%.
