What is tyre pyrolysis?
Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen （or any halogen）. It involves the simultaneous change of chemical composition and physical phase, and is irreversible. The word is coined from the Greek-derived elements pyro “fire” and lysis “separating”.
The pyrolysis method for recycling used tyre is a technique which heats whole or shredded tires in a reactor vessel containing an oxygen free atmosphere and a heat source. In the reactor the rubber is softened after which the rubber polymers continuously break down 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. Some molecules are too small to condense. They remain as a gas which can be burned as fuel. The minerals that were part of the tire, about 40% by weight, are removed as a solid. When performed well a tyre pyrolysis process is a very clean operation and has nearly no emissions or waste.
Pyrolysis of scrap or waste tyre can separate solids in the tire, such as steel and carbon black, from volatile liquid and gaseous compounds that can be used as fuel. Although the pyrolysis of waste tyre has been widely developed throughout the world, there are legislative, economic, and marketing obstacles to widespread adoption.
Waste Tyre Caused Serious Environmental Pollution
Only in the EU, USA and Japan around 6 million tones per year of scrap tyre are produced. The huge quantity of waste tires presently produced in the world will certainly increase in the future as the associated automotive industries grow. The disposal of scrap tires becomes a serious environmental problem. The accumulation of discarded waste tires leads to environmental pollution. A large fraction of the scrap tires is simply dumped in sites where they represent hazards such as diseases and accidental fires. Rubbers are not biologically degradable, and this fact creates problems with their disposal. The impact of waste rubber on the environment can be minimized by recycling with material or energy recovery. However, during processing and moulding rubber materials are crosslinked, and therefore they cannot be simply again softened and remoulded by heating. For many years landfill, was the main, practical means for dealing with the problem of waste tires. However, landfilling of tires is declining as a disposal option, since tires do not degrade easily in landfills, they are bulky, taking up valuable landfill space and preventing waste compaction. Open dumping may result in accidental fires with high pollution emissions. In the EU countries in 1990 the percentage of tires discarded in landfills was 62% of all produced waste tires in 2000 about 35% and in 2006 （as it results from the EU legislation） this percentage will decrease to 0%. Some countries including the Slovak Republic have already banned the use of discarded tires for landfilling.

Pyrolysis Plant Can Help You Get A Lot Of Wealth
Pyrolysis means 100% recycling of tires: All high valuable raw materials are extracted smoothly. Tire Pyrolysis harvests 4 “Green“ products: Carbon Blacks （CB）， Steel, Oil, and high caloric combustible Gas, which can be used for generating electrical engergy, heat, steam, or hydrogen.
The international market price of quality virgin CB for rubber applications （made from oil） is approx 1.500 USD/t and a huge demand already exists （8 million ton p.a. worldwide）. Rubber granules has limited demand and a market price of 100 to 200 USD/t and it is difficult to sell.
Tire Pyrolysis delivers clean steel after processing and sells for regular scrap price approx 300 US$/t, steel from rubber shredding/grinding has still too much rubber attached what the profit let decrease.
Tire Pyrolysis harvests Oil & Gas adding substantially higher revenue of approx 350 US$/t. Tire Pyrolysis processing plant need very minor maintenance in comparison with the heavy Shredding Machines who makes rubber granules. Costly knifes etc. to be renewed frequently.
The world Oil prices will increase but recycled CB will have stable prices so it’s price advantage is even higher in the future. Same economic point applies to the recycled steel, oil and gas.
Tyre Recycling Plant Working Process:
* Put the raw material into the furnace
* Seal the feed inlet then the bottom of the reactor will slowly heat the wastes by coal or electricity
* When the temperature reaches the degree of 250 to 280, we will get the crude oil
* The oil steam will be continuous produced until the temperature reaches 300-400°C
* Oil steam will flow through light and heavy components separating device
* Light component will enter the condenser and meanwhile the residues will be discharged automatically in succession
* Liquefied part will be condensed to rubber oil
* The part that cannot be liquefied will be input into heating supply system for burning by way of combustion gas purification system.

Domestic Initiation Of Tire Recycling Machines
a. The complete set of unit produces no smoke and smell with favourable effects of environmental protection.
b. The pressure release device operates through water circulation, which greatly improves the security of the system.
c. The release of pressure during the production dramatically increases the output within certain time and meanwhile improves the quality of oil .
d. The heating system adopts hot air heating technology, which improves the safety performance of production and heating efficiency.
e. High efficiency fuel gas heating system. When the heated gas reaches 150 during refining, a large amount of gas will be generated: through methane to butane, which cannot be liquefied under normal temperature. A large quantity of energy will be generated after these gases fully burn within a specially designed gas burner. Then energy will be saved greatly.
