| Abstract: | Kaoline clay and amorphous silica alumina have been studied as catalysts in the degradation of
waste Thermocol (Expanded polystyrene) in a stainless steel autoclave surrounded by a furnace
at different temperatures ranging from 350-5500C under partial oxidation condition. The major
fraction of the pyrolysis reaction is an oily liquid, which is highly volatile. The reaction time
decreased and the yield of liquid fraction increased with the increase in temperature. In the
pyrolysis optimization studies, the highest yield of liquid product obtained is 93% in thermal and
94.5% in presence of clay catalyst at 5000C with 1:10 catalyst to plastic ratio. Kaoline clay
shows a slight increase in liquid yield whereas silica alumina gives the same with regard to the
thermal cracking. The liquid product has been analysed using fourier transformation infrared
spectroscopy and detailed hydrocarbon analyser. In addition to styrene the other major products
present in the liquid fraction are b... |
