| (ZSM-5)Catalytic
pyrolysis of tyres: influence of catalyst temperature |
|
|
|
Two stage pyrolysis¨Ccatalysis of used tyres was undertaken to
upgrade the derived oil to a highly aromatic oil suitable to
be used as a chemical feedstock rather than a liquid fuel. The
tyres were pyrolysed in a fixed bed reactor and the evolved
pyrolysis gases were passed through a secondary fixed bed reactor
containing zeolite catalyst. The pyrolysis reactor was maintained
at 500 ˇăC and the influence of catalyst temperature between
430 and 600 ˇăC on the yield and composition of the derived oils
was examined. |
| Pyrolysis of scrap
tyres with zeolite USY |
|
 |
zeolite catalyst of ultrastable Y-type (USY) was investigated
in the research of two staged pyrolysis¨Ccatalysis of scrap tyres.
Scrap tyres were pyrolysed in a fixed bed reactor and the evolved
pyrolysis gases were passed through a secondary catalytic reactor.
The main objective of this paper was to investigate the effect
of zeolite USY on the yield of products and the composition
of derived oil. The influences of several parameters such as
pyrolysis temperature, catalytic temperature, catalyst/tyre
ratio, heating rate, etc. on the yield of the derived oil, char
and gas were investigated. It showed that the increase of catalytic
temperature and catalyst/tyre ratio resulted in high yield of
gas at the expense of the oil yield.

| Pyrolysis
of waste tyres with zeolite USY and ZSM-5 catalysts |
|
|
Pyrolysis of waste tyres was
carried out with a two-stage bed reactor. The waste tyres were
first pyrolysed in a fixed bed reactor, and then the evolved
pyrolysis gases were passed through a secondary catalytic reactor
filled with two types of zeolite catalysts, which were ultrastable
Y-type (USY) and ZSM-5 catalyst. The catalytic temperatures
were examined to determine their influence on the yield of product
from the pyrolysis¨Ccatalyst of waste tyres. |
