Thermal pyrolysis is one of the renewable technolog
ies where waste tyre and tube were
pyrolysed into fuel oil, carbon black, and combusti
ble gas under the action of reasonable
technological conditions. This technology could not
only reasonably and effectively dispose
waste tyre and tube without pollution, but also is
effective in producing fuel that can reduce
energy crisis. In the present work, thermal pyrolys
is of waste bicycle tyre and tube samples were
carried out in a semi batch reactor made up of stai
nless steel within the temperature range of
450ºC to 800ºC. The optimum pyrolytic oil of 49.6%w
as obtained at 600ºC for tyreand 49.65%
for tube at 700ºC. Again to increase further oil yi
eld, different catalysts have been used

the catalytic pyrolysis was not
effective when compared to thermal pyrolysis in ter
ms of product yields (oil).The physical
properties of the oil obtained were determined by u
sing standard test methods and the chemical
composition was analyzed by using FTIR, GC-MS analy
zer. The char obtained was
characterized for its calorific value and surface m

the oil showed the presence of aromatic and aliphat
