A study on the thermal and catalytic pyrolysis of plastics

Thermal and catalytic pyrolysis of plastics have been carried out. The thermogravimetric analyzer(TGA) and batch type laboratory scale catalytic reactor were used as experimental rigs. Pure or waste plastic samples(HDPE. PP. PS. ABS). collected from domestic industry were used for the experiment. The powder of silica alumina (50ｇ) was used as catalyst for pyrolysis. The experimental results showed that the decomposition temperature was increased with an increase of heating rate. because of time lag associated with heating of plastic samples. It was also found that the maximum decomposition rate and decomposition temperature of HDPE are much higher than those of other samples.
