4. We are going to represent a tire pyrolysis oil industry of
Bangladesh which is Radiant Renewable Energy Limited
(Gazipur,Bangladesh) .
5. What is Pyrolysis Oil ?
Pyrolysis oil, sometimes also known as bio-crude or
bio-oil is a synthetic fuel under investigation as
substitute for petroleum. It is extracted by bio-mass to
liquid technology of destructive distillation from dried
bio-mass in a reactor at temperature of about 500 C
with subsequent cooling. Pyrolytic oil is a kind of tar
and normally contains too high levels of Oxygen to be
a hydrocarbon.
6. As we know Petroleum is used so much all over the World
and It is a natural gift which will finish by the time being.
The price of petroleum is increasing day by day so the
pyrolysis oil can be a substitute of it. Moreover the price of
pyrolysis oil is much lower than the petroleum and other
fuels. So the increase of the production of pyrolysis oil is
necessary for the present progressing world.
7. OBJECTIVES :
The Raw Materials.
The Process of Tire Pyrolysis.
Productions.
Waste Management to Save the Environment.
8. RAW MATERIALS
Waste Tires :
Waste tires are the main raw materials of
producing pyrolysis oil. So we can call tires the one and
only element of tire pyrolysis.
9. There are some more elements which can be use as tire
pyrolysis oil production.
Those are :
1. Rubber or rubber parts from vehicles .
2. Electronic scrap.
3. Mixed (HDPE, LDPE, PE, PP, Nylon, Teflon,
PS, ABS, FRP etc) Multi layered.
4. Plastic disposable bottle.
10. WORKING PRINCIPLE
Pyrolysis, essentially an endothermic process, an
environmentally attractive method for the treatment
of tire wastes. The process uses medium temperatures
(400 ~ 500oC) and an oxygen-free environment to
decompose solid tire wastes chemically, thus
producing minimum emissions of nitrogen oxide and
sulphur oxide compared to the commonly practised
conventional technology, incineration. Pyrolysis also
allows valuable materials to be recovered.
11. Pyrolysis is a thermal degradation process in which the
solid tire waste is heated indirectly in an oxygen-free
atmosphere. The whole process is the sum of a series of
parallel and subsequent reactions that take place in the
pyrolysis reactor. The most common rubbers used for tires
are natural rubber (NR), styrene-butadiene rubber (SBR)
and butadiene rubber (BR). The rubbers consist mostly of
blends of two or three rubbers, together with minor
constituents including oil, plasticizer, and other additives.
All of these constituents lose their weight at different rates
and at different temperatures when pyrolysed. A review of
the available international literature and the laboratory
results show that the decomposition temperature is about
150-350oC for processing oils, plasticizer, and other organic
additives, 330-400oC for NR, and 400-480oC for SBR and
BR.
12. decomposition model, is presented in
Fig. 1. The three types of arrows in the
flow diagram indicate three
decomposition reactions. The higher
weight or color deepness of the arrows
indicates the decomposition of the
corresponding tire material in the
higher temperature regions.

20. WASTE MANAGEMENT
Carbon :
Carbon black produced by Pyrolysis process
(CBp) is more economical compared to carbon black
produced primarily from and is more price-efficient to be
used as an ingredient in the industries listed below:
21. 1. Electric cable jacketing,
2. Conveyor band,
3. Carrier Bands,
4. Hose and doormat,
5. Black nylon bag,
6. Rubber additive,
7. Automotive spare parts,
8. Heat isolation,
9. Fire fighting,
10. Black colorant in rubber materials.
22. STEEL WIRE :
The steel present in the tyre can be detached
after pyrolysis recycling process is completed. Valuable
steel wires are pressed and sold to steel and scrap dealers.
23. CONCLUSION
The liquid bio-oil product from fast pyrolysis has
the considerable advantage of being a storable and
trans- portable fuel.Pyrolysis oil has been
successfully used as boiler fuel and also showed
promise in diesel engine and gas turbine
applications.Some chemicals, especially those
produced from the whole pyrolysis oil such as steel or
carbon offer more interesting commercial
opportunities.
