- Pyrolysis is the thermal
degradation of materials containing carbon. The process is carried out
usually at temperatures in the range of 400 C to 600 C in an atmosphere
in which oxygen is very limited or excluded to preclude combustion. The
products of pyrolysis include gas, liquids and solid char
- Three
commercially important pyrolysis by-products from vehicle tires are
liquid
oil, solid char, and exhaust gas.
-
A typical passenger car
tire contains 24-28 percent of carbon black, 40-48 percent of natural
rubber (NR) and 36-24 of synthetic rubber including styrene butadiene
rubbers (SBR) and butyl rubber (BR).
-
The disposal of rubber waste, such as
that from used tires has increasingly caused in a serious
environmental problem. Each year about 10 million tonnes waste tire
rubber were disposed of all over the world, and approximately 40
thousand tonnes every year from China and only 10 % are recycled
-
About 300 Million tires are
recycled annually in the USA
- There are good business Opportunities
for development of pyrolysis technologies of waste tire
rubber due to environmental pressure and economical driving force.
Techniques developed were recently characterized by small-sized device,
lower cost to
construction and operation, easy to transfer and disperse where it is
needed.
- About 30 inventions on
the pyrolysis of waste rubber were patented in P.R.China.
-
There is one patent application from
India too
-
Thermal pyrolysis is a process used for
tire recycling. It splits
complex materials into desirable ones under high temperature, i.e. turns
rubber into oil, steel and carbon powder. Development of effective
pyrolysis technologies
has been going on since the early eighties but the high temperature of
the process (typically 700°C -
800°C) has so far led to poor quality of the recycled substances with
low commercial value. - It
is further claimed that the decreased temperature of
the process prevents complex hydrocarbons from thermal destruction,
which happens in traditional processes conducted at higher temperatures. -
100 Tons/Day plant is estimated to cost
USD 30 Millions
- The reclaimed
oil could be used for fuel or petroleum products, the carbon black for
inks, dyes or rubber or plastic products, and steel for automobiles or
construction materials
